anxiety

i have social anxiety and its pretty bad. school is starting kinda soon and im so worried about going back. i always wanted a fresh start and a new year is exacly that but im not sure i can do this anymore. i barely got through last year, failing almost every class, missing a shit ton of school, i dont think i can do it anymore. i found out im in a class full of people i dont know. all my friends are in different classes and i asked one of my parents to request a class change, something you can do in my school, but they refused.

my anxiety and mental problems are something i always hid from people but i finally told my parent and they completed bushed me off. they said that i wasnt sick and i was saying all this to get sympathy and skip school but all i want is to feel comfortable in school and be with someone who makes me feel comfortable around them. i dont know if theres something wrong with me. i dont know if im just doing this for attention

they told me i shouldnt get special treatment and that if they could take it, that i should as well. "thats life" is something they said and i can agree with that. i get that sometimes you will have to be in situations where your uncomfortable and alone but for me its so unbearable when i am, that i cant breathe and i want to throw up and thinking about spending an entire year like that, i cant even imagine myself doing that.i dont know what to do. i want to go to therapy for this so i can get atleast better, but i have no clue how to bring it up. i have no one to tell and im not old enough to schedule my own therapist? is it serious enought to go to a therapist. is my parent right, should i just deal with it? . i feel bad for making people deal with these kinds of things for me and being such a burden. i dont even know if my freinds want to be in the same class as me.

how can i get a therapist? an how can i convince my parent to talk to the school about this?

should they?
