i don’t know what this is anymore

i’ve has anxiety for years and have struggled on and off with depression. for 6 years i was a 2-3 hour a day 6 day a week type athlete and while it helped ease my anxiety it was not a healthy situation, i started feeling as though i was going numb. i haven’t trained in a long time (i will be training again but only 2-3 days a week for a couple hours rather than 6) and my emotional and mental health has been deteriorating. anxiety has always been something i’ve dealt with but this has become a lot more severe. i have to leave almost every class almost everyday and pace around the school bathroom to try to stop myself from having a panic attack and i get really emotionally distressed very quickly. i break down crying constantly and have to stop myself from getting worked up. i’m an introvert but lately i’ve been spending a lot more time alone. i’m constantly tired and anxious and sad and upset and depressed and it feels like it’s more than just my usual anxiety. do any of you have any idea of what this could be? i know it may sound silly and arbitrary but it’s gotten really bad and i need a solution.
