My last year of secondary school

When I was a child in school I found it hard to fit I and to make new friends it's I have a disability named autism it's harder to approach others when. Now I'm in my last year in secondary school there's some nasty people who mock you and your just stuck in a room that makes you want to escape because no one stands up for me and no one never understood and listened to me when I tell them to stop they don't and I feel explosive and about to scream in rage because I feel like I'm not respected and valued appreciated by the orhers but only the teachers would understand why I swear at someone back when I'm standing up for myself and I find it hard to ignore people who keep calling my name so many times trying to get a reaction out of me! Why does it have to be me that has to be messed with!??
