5th and 6th grade bullying

So when i was in fifth grade it all started when my friend i thought i could trust teamed up with the person who would bully me daily and i would go home crying every day because of her. Then those two girls somehow turned everyone against me to the point when i didn’t even and still don’t know all of the rumors created about me. Ever since then i’ve been scared of not being enough for people and i just don’t know what to do about it. In 6th grade there was a guy that assaulted me. I have a boyfriend now and i trust him a lot and he always reminds me that he really wants to spend the rest of his life with me. More girls bullied me and also that year my first ever guy teacher would be really gross and inappropriate to me and all the other girls in my class. So now one of my friends has been dealing with depression and he would tell me all these things and it would trigger “asthma” attacks and i would just randomly break down during school. I decided to tell my friend to instead of talking to me about it, talk to adults that can actually help him. Ever since then he’s been telling me all these things about why my boyfriend is a horrible person and everything he says isn’t true. Now i always feel no matter what, that i’m not enough and no one will ever love/like me because i deserved what i got and i don’t know how people could even think i’m an okay person because of how paranoid i am. Thanks to everyone that even read to this point.
