If anyone takes the time to read this, thank you. I just need some advice from anyone right now.
I feel alone. I feel like sometimes my friends treat me well, and that we are super close, but other times it feels like they don't care about me, and that all their other friends are better or more important than me.
Sometimes one of my friends will talk to me, but if someone else comes, I get ignored. I'm always the one walking behind the group, getting ignored, and left out.
And it's even worse because I only have about five or six friends, and all of them are like this. Sometimes they are super nice, other times I get ignored.
And sometimes I wonder if they really are my friends. Sometimes I wonder if it's just my crazy imagination and they really do care about me. Sometimes I feel like I should just not be their friend anymore, but then I would be completely alone. And other times all I want is to be with them.
It's confusing, and it's painful. I don't know what to do, and I have been feeling this way for years. Please, if anyone can, I really need some advice. It would really help and I would really appreciate it. Thank you.

This used to happen to me a lot. It stopped randomly, but I think you should have a good talk with your friends and see what exactly is going on. If you're close they should answer. Without asking them directly, I doubt you can figure this out and put an end to it. Good luck~

I think you should stick behind the crowd and eventually remove yourself. It may be beneficial to show them what they are doing by speaking with the lack of your presence as they normally expect. Instead of accepting the terms they put on the table instead put yourself in situations that would put you in the lead role. Silence is power but closed mouths usually don't get fed keep it balanced.

Friends come and go but family is forever. You should not worry about your friends. If it is attention you want, then your family is the only group that will give you as much as you crave. If you don't think your friends are really your friends, well... It's best to be alone than to have a bunch of bad friends. Take it from me. I've been there.

You're the type of person I like. Lets be friends. I think that this is not an uncommom issue. You probably feel like the "backup" friend if noone else is there. I do say that people do that all the time to one another. Sometimes they don't mean to be like that but nevertheless it happens. A simple thing could be to simply ask them. If they truly care they would lend you an ear. I would say also try search for other friends, I know that sounds bad but you never know who you may meet.

Thank you all so much, this really helped me. I really appreciate that you all took the time to help me. A new year of school is starting soon, and maybe I can make new friends. And maybe I will talk to my current friends about it. Thank you all so, so much. :)

You're welcome anytime at all :). Take it easy :)
