<human>: Could you distill the essence of the text into 1-3 sentences?

I've been friends with these people for varying lengths of time, the longest one is 5 years and the shortest is 2, but they don't like me. It's not teasing or anything like that, it's the lack of any communication whatsoever.

In school (we're freshmen) they'll talk to me, but they rarely initiate the conversation. On top of which, it always seems like I'm more ignored. Like when we're walking three across on the sidewalk I'm the one constantly pushed off. Or if we're taking in class I'll struggle to be able to say something that they'll listen to.

Whenever I'd try to invite one of them over or just out to do something, I get a "I think I can't this weekend." Then on Monday I'll hear them talk about how they did all this shit together on Saturday or something like that. They also rarely respond to texts. Like I texted my friend yesterday and he still hasn't responded. But he's not too busy to respond to other friends (I was talking to another friend and they laughed because he sent them something funny).

And when it really started to sink in was when I found out that our group of 9ish friends were having a party. Who's the one not invited? Me. Yes, I'm the one who is sitting home alone on Halloween while his friends are hanging out with each other. It's a pain that can't be described. My life sucks in other places too (I'm feel useless constantly, I'm clumsy, I'm overweight at 6' and 180lb, etc), but this is by far the worst. If I didn't have a family who cared I don't know how long I could keep going.

How can I fix this? I'd have no other friends if I left the group and I feel like that'd be even worse. Please help.
<bot>: Friends of up to 5 years have been ignoring me and stopped spending time with me. I'm left depressed and confused.
