I didn't know what to call this. I don't even know how to really say what I want to, so I'm just going to be direct. I haven't slept well in days. I have no friends, I'm not close to any of my family. I don't feel welcome in my own home. I just feel weird.

gonna have to start fresh my friend. You don't owe anyone anything and if you don't feel welcome drop em and start new.

>>1 Step One, get your shit together and know what your doing
Step Two, stop typing "I" at the start of every sentence

Insomnia could be due to stress or an overactive mind (probably stressing about being weird), honestly the only ways to cure insomnia is either get rid of your stress of take melatonin pills.
Friends are quite literally overrated. You don't have to love your family for them to be family. This sounds a bit callous, but it is the truth. People make a big deal about making friends and loving your family no matter what, but that is just false.
Right now I think your problem is that since you have no friends or close family you lack an outlet for you to take out your pent up frustrations.
I would suggest finding something that'll make you cry. (Not self-harm!) Try reading or watching something that's really sad. This is what I do because I actually have a very similar situation. However, I'm not trying to cure my insomnia because insomnia is proven to make the creative side of your brain more active and I like to write fantasy novels which require a lot of creativity. Try writing something yourself maybe if you like doing that type of stuff.

>>3 Seriously, you are incomprehensible.
A new start or a change in attitude is what you need. Try to view things from a different angle or start a new activity, maybe joining some clubs or something like that.
You could also move to a place far away from your past and start anew, but I guess you're unable to do that.

Is there a problem with beginning every sentence with "I"? I'm not old enough to move, so I cant drop em and start new or move to a place far away and start anew. I've been trying this thing, that I'm kinda liking.. I just simply do whatever I want, and as long as I don't step out of line too far (like killing someone or something) I think it's fine. If I want to take another trumpet lesson from someone even though it means I cant take my sister to her doctors appointment? I'm gonna do it. If I want to have an entire day of sitting on my laptop reading/watching/playing whatever and only getting up to use the bathroom or eat? I'm gonna do it. It's how I've been living since I last posted. I dunno how it'll affect the friends situation since I haven't been around anyone besides my family since band camp ended, but it's at least helped me handle my home life better.

If you're fine with that, sure, why not.
