Anxiety attacks

Lorelei

I am 13 so I’m in 8th grade and ever since I have been in middle school my anxiety attacks have gotten worse. In the middle of a test I start balling my eyes out and freaking out and I ask to go to the bathroom and I sit in there for 10 mins and I text my mom and she just says calm down. The only person that can help with my anxiety attacks is my best friend. What should I do about the anxiety attacks? My mom says I can’t get a therapist
