Short version: I'm forced to work in a group of people who are nice to me but actually dislike me.

Disclaimer: I'm sorry if you get bored while reading; I just want to type this all out. This has been eating at me for a while.

Long version: I have been in this school activity my whole time in high school. It's a fairly large organization with about 100 or so kids in it. This particular organization is marching band. Everyone has to work with others who play the same instrument as them for obvious purposes.

I have know the people who play the same instrument as me for about 4 years. We were never best friends or anything, but good acquaintances I suppose. So this all sounds good and a little boring, but of course it's not as clear-cut as that.
They all became fast friends from day 1 of band; exchanged numbers right away (I don't have a phone) and made up cute little nicknames for each other. They're in all the same classes together (I'm in honors classes and basically never see them except in band).

None of this really bothers me except they also get together outside of band all the time. I only know this because other people ask me things like, "did your section have fun yesterday? Those pics on Instagram made it look really fun". I just feel like a complete idiot when I say that I have no idea what they're talking about, even more so because I think mine is the only section that leaves people out like this.

But it doesn't even stop there. They don't invite me because they're unfamiliar with me, forgot to, etc., but because they think I'm too weird and immature. They think I'm so weird that whenever I respond to one of their question they think I'm lying because my responses are so strange (and now they never believe me). They think I'd rat them out (they drink and smoke and probably other things) if I was ever invited because I care about schoolwork and my GPA.

There was one particular instance where I was invited to one of their little get-togethers over the summer. At first I thought one of them actually was beginning to like me but I quickly found out that it was their mom that had invited me. Her daughter had only agreed because she didn't want her mom to uncover her purposeful ostracizing of me. I sort of anticipated that the sleepover would turn out badly (I also had no phone to call my mom to pick me up in an emergency) but I figured that I wanted to end my senior year on a good note. I anticipated correctly. One of the worst moments was when we went into the hottub (my swimsuit was quickly questioned for how it looked; I explained my elderly grandmother was with me when I got it but of course I wasn't believed) and started to play Never Have I Ever. How the game goes is someone asks a raunchy question (i.e. never have i ever had sex while high) and if you've done that thing before, you lose a point (everyone starts with ten). Needless to say I "won" because I had all ten points. Also the question could be directed at people, and everyone took the opportunity to grill me.

The hottub thing was terrible, but there were moments where I got to talk to them individually. They're not bad people and I can even see me being friends with one of them had we met under different circumstances, but as a group they are toxic.

No, I'm not being paranoid or jumping to conclusions. Just from short fragments of what they say to each other, how they choose to hide jokes from me, or even how little patience they have when explaining something to me is enough for me to come to this conclusion.

Yes, it's very stupid of me to get upset over this. I have my whole life to get drunk, smoke joints, and give blowjobs; high school is only 4 years long. But band is a huge part of my life and requires cooperation for it to work. This is my 4th year of being in the same section as these people and all I can say is that I'm very grateful that this is the last year.

tl;dr toxic people only last so long. Any additional advice on how to make the remainder of my year more bearable?

Don't worry too much about it.
First of all, honours students always have it worse, everyone seems to hold some sort of grudge against those that achieve more. It's human nature.
Second of all, musical communities are a difficult place to fit in and actually 'enjoy'; because from my musical theatre and band experience, while being fun, performances and rehearsals can also be very stressful (hence revealing the 'true' qualities of some people).
My advice is to just take it nice and slow. And it is wrong to think of someone as 'toxic' just because you assumed that they don't like you.
Just try not to hold your head too high and seem like a prideful dude OR be a shy awkward guy that always get left out.
Find the right balance.
and then again always analyse the people.
They might not be worth that 'fun' in the end.
sincerely,
1289.

It seems that more than two people go by this name.

Hello,
I would not spend time worrying about them and i agree with 1289. I also would not jump to conclusions that they do not like you. Chances are they do like you but you havent build a strong enough bond with them. I would suggest being friendly with them and try to talk with them more little by little. Perhaps showing them that you are interested in being included and spending time with them they will warm up and invite you next time. You could also invite them to do something fun together so you can get to know them better. I know what its like to feel like the odd one out but sometimes what we perceive is not always correct and chances are they do not dislike you. I could be possible that they think you do not want to hang out with them based on a vibe you are giving off

>>3 As I was reading the OP, I did find it a bit odd to be coming from you.

>>1 I have a similar situation, but nowhere near as bad. I am a junior in high school, and this is my first year in a band, so I was placed in one with all freshmen. They have all known each other for years of middle school band, meanwhile I'm the oldest in the band and don't even really know anyone in the school. It is really hard to be in a group that you don't fit in, and won't let you in, but sometimes it's better not to become one of them. For you, you said that they all drink and smoke and stuff when hanging out, and don't invite you because they think you'd rat on them. Are they even the type of people you want to hang out with? You are an honors student, and things like drinking and smoking in high school could ruin the rest of your life! If they are caught, they will almost definatley go to jail, and will have an incredibly hard time getting a job in their future. If they make the mistake of drinking and driving, and they hit someone (which is highly probable), they could get 20 years in prison. They may not care, or foresee a life past high school, but you should. Honors students may not have a good time in high school a lot of the time, but they are the people who become truly successful. Let me ask you, would you rather be popular for a few years of your life, or would you rather live your life being successful and respected? High school difficulties are hard to deal with, but if you can endure and make it through, your future will be much brighter than a prison cell. I hope this helps!

Just approach them and tell them that you want to be friends it's obvious that you want to do so
