Anxiety help

Well I've been told it's likely that I have an anxiety disorder, and I never open up about anything so tonight I decided to tell my mom. She literally laughed in my face and turned it into this huge joke. She won't make me a doctors appointment because...

she thinks I'm lying. What should I do?

well sweetie, I have an anxiety problem too.
the medicine they give you at the doctors don't really help either.
if you get upset or anxious about it just try to breath in and out slowly and put it in the back of your mind, or go to your school nurse if it keeps getting worse.

Welcome to my world (pours you a cup of hot water for tea.)

Speak to a counsellor at school and tell her what you told us. If you feel overly anxious you should get help for it. And parents for some reason tend to listen better to people that are not their kids.
