What do I do?

I’ve been having anxiety and attacks during school. I hold in emotions and don’t let them out. I try to tell my mom how I feel and how I feel pressured to be the happy person I always was. I am not happy anymore that that’s who people think I am and if I am sad or want time alone nobody respects it or is in face asking me if they can do anything. I told my mom about this and she said it was hormones acting up. I told her it was happening before all the hormones. She stuck to her word and still believes that it’s hormones. I want to see somebody but if my mom thinks it’s nothing she won’t schedule anything and I can’t legally do it myself. I’m afraid to tell my dad because I have no clue how he would react. I have know clue who I am or what I want from life anymore.
