I probably need new friends

School starts for me in a couple of days and I'm dreading going back cause of my friend group don't get me wrong they are good people I just don't think they are for me.  I can't express any of my interests without getting called a poser, a 2020 alt kid, emo, or a loser and I know they are joking most of the times but sometimes I feel like they are not joking and every time I bring it up, I get told that they are joking or don't be so sensitive and I know I probably am being sensitive but I don't like being called names cause it reminds me of what my family calls me so it makes me feel bad about myself.  Like I know if I just show up one day with a tail I made and some ears, I bought that they would be looking at me weirdly or just make fun of me and I don't know how to deal with it.  To make matters worse my best friend barely talks to me anymore he only talks when he has a problem or when he wants to show me something, but he is never there for me or if he is he takes hours sometimes days to respond and it just hurts cause I see all these friend groups that have people who support each other and don't make fun of each other and I get jealous cause when is it my turn to have that type of friend group all the friends groups I been apart of they basically stop being friends with me cause I'm too weird, stop being friends cause I'm not weird enough, I had a friend stop being friends with me the minute I turned 18 and basically called me a pedophile, stopped being friends with me cause I was the only non-mentally ill one, or stopped being friends with me cause I'm the only black person in the group.  Like I'm about to be 20 and I haven't had a real friend group or real friends ever in my life
