I have tried to talk about this a couple of times, but I never know how to word it in a way that best fits the situation. To put my "issue" in a simple way: I'm always lethargic. Every day, in one form or another I always start off the day beng tired, and stay tired the rest of the day.

I lack the motivation to start any passion or interest and go through with it. Now I just mope around in my room. I pick up some activities and drop them. I don't have passions, or anything I feel very invested in.

Most of all: I have a lack of focus. It gets so hard for me to concentrate sometimes. Especially now, late at night, I have difficulty trying to put this issue into words. It's been getting increasingly harder to concentrate over the past year. I've noticed this problem getting worse later on in the school year.

This is getting annoying. I see all these people expressing their passions while I have none. I don't understand how people get so motivated. I haven't had a feeling like that in a while. In fact, I don't think I've ever felt like that. But I'm rambling. This is not the issue.

In short, I have trouble focusing, and always feel tired, preventing my enjoyment in life, I guess. Not being able to focus is annoying. It's like I have this fog in my mind. "Brainfog" as you would call it. It's just a lot worse now, bein nighttime, but I have this problem in the daytime also. Can anyone give me reasons for why I'm like this? I've done a little bit of research and changed my sleep schedule a couple of times, but it didn't get rid of the fatigue. This may contribute to my lack of motivation.

None of this is necessarily "severe," but bad enough to the point where I don't think it's normal.

No other symptoms?

When was the last time you've had a visit to the doctor? Have you had your vitamin D levels checked? I was very much the same as you and it turned out that my vitamin D levels were very low and that was causing my depression to get worse than it usually was. That being said, it could also be depression. Keep in mind that depression does not always have a reason, sometimes people just feel depressed without a reason.

Eat sugar.

I feel like people aren't looking at this the right way. This is more of a mental problem than a physical one right?

There's a lot of factors I'm missing because people's situations and lives are not simple, but I'll still try to help and just hope that it's relevant. If it's a physical problem then feel free to just ignore the rest of my message ^^

So would you say that this feeling you have might be due to being empty? If there's nothing that interests you and you really have to force yourself to do things, then it makes sense that you would be lethargic and find it hard to concentrate. Whether you want it or not, you involuntarily don't see any point in doing these things. Or at least this is how I see it.
Some people just don't fit with the way of the rest of the world and need something different. My suggestion for a hobby, and possibly more, would be something involving the creation of something new, or adding something new to the world. Things like art, writing stories, creating music, etc.
These things become a part of you as you create them so you start to feel more inside if you start creating them. You don't start off being fulfilled, or at the end of your journey. You have to take the first step, you will make progress over time and things will build up over time.

But all of that aside, I think it might just be good to put a lot of time thinking about this in general. We don't see the whole story and know all of the factors, as well as that our experiences and range of knowledge will vary greatly to yours. We can give our thoughts and try to help, but if we can't then it's up to you to figure this out for yourself.

I hope that wasn't too extreme or weird. Best of luck though ^^

>>4 Could be physical.

>>2 I don't have any friends, and haven't had any friends in a couple of years. This is because I find that trying to keep up conversation can be tiresome, and there are many days where I just don't feel like talking. I'm a loner, as you would call it. I still talk to my family occasionally despite this.

>>3 It's probably been a few months, and even then I had not spoken about this issue. I had not had my Vitamin D levels checked. Of course, I very rarely go outside. My vitamin D levels may be very low.

>>5 I've actually tried to pick up those hobbies before (aside from music) and I dropped them very quickly. Maybe in less than a day.

>>4 you know, that could actually help.

Regarding depression, I feel like I am becoming less and less motivated to do much of anything over the year. I'd still do some outdoor activities with my family, though. Unfortunately, I always feel tired when doing this.

I think for me, life is starting to lose its value. This is the only way I can explain this. I feel less inclined to keep up activities that people are more motivated to do. I'm not sure if this philosophy on life is worth mentioning, though. This could very well be the result of overthinking.
To elaborate further on my lack of concentration, I would like to mention feeling detached from other people and my surroundings. I don't know how to explain this correctly. It feels like I don't feel completely awake, like I'm not 100% aware of what I'm doing. As I've said, it's like a fog in my mind. It's like I'm not 'into' activities as much as most other people are. This also contributes to my apathy for my social life, as well as my reputation at school. Other kids in my school seem to care about social activities, while I don't even know what events are going on at school...
When I'm trying to concentrate on something, it doesn't take kong for me to lose focus. Listening to my teachers became increasingly harder. I end up zoning out completely, unless I'm tajing notes. When I read, I end up daydreaming. When I'm watching anime, I tend to forget some things that are important that was explained before. I have trouble hearing when watching films on television, so I always need captions. I also zone out a lot when watching films. I can never be completely focused when doing activities, which is why I'm so forgetful.

I rambled again.

>>7 Eat it. It produces energy, which is either converted into fat or used up.

>>3 Depression seems to be a keyword here.

>>7 Have you ever heard of Asperger's Syndrome? I may be wrong, but from what you said I think you may be an aspie, and a depressed one.
This quizz is very trustworthy, I have tested it: http://psychcentral.com/quizzes/autism.htm
If you score 34 or more let me know, then I may help you further.

>>9 I have heard of Asberger's Syndrome. In fact, last year I was suspected of having it, and my family, for a period of time, seemed to have believed it. They had gotten over it rather quickly, though. I don't think I have Asberger's Syndrome.

I scored a 31.

I think this is more a mental thing. I have a similar situation, though not nearly as acute as yours. I'll be doing something, drawing or listening to music, and I'll just stop... paying attention to it. I zone out, stare into space, but I'm not thinking anything specific. I used to think it was an attention deficit or something serious as such.
This issue comes and goes for me, although the over-arching feeling of detachment is constant. I play a lot of videogames and read a lot to try and fight this, and I wrap myself around schoolwork with a will, and I also try drinking lots more water, going outside (I like going swimming, in outdoor pools, even if it's just to float there and catnap. I'd suggest this if its some sort of vitamin D deficit, as it's still comfortably 'lazy' and doesn't force you into action).

I hope this helps, and even if not, good luck!

>>10 If you scored 31 then it's still a possibility, maybe would be a good ideia to look for a diagnosis, I think a better understanding of yourself would help quite a bit.

But if you don't think you have Asperger's then you may have another place on the spectrum. I suggest the site wrongplanet.net, lots of useful stuff there.

By the way, I don't have a diagnosis myself but in that particular quizz I tend to score around 36~38 if I make it honestly. It's trustworthy because I sent it to some neurotypical friends of mine and they usually score around 16 points.
