Social anxiety??

I've been diagnosed with generalized anxiety, ADHD, and Tics but I think I may have social anxiety instead of generalized and heres why. There are many times I feel anxious in a big group of people but I'll just list a few of the worst situations. When we play team sports in PE I sometimes start shaking and having a sorta anxiety attack bc I'm so scared of embarrassment/failure, sometimes I'm scared to get up in class to go to the bathroom cuz when I come back in someone will be staring, and I am self conscious and always think I know what someone else is thinking badly about me. Those were just a few things but could anyone who has been diagnosed with social anxiety just let me know what some other symptoms are?? Thank you! (I am not trying to be ignorant and self diagnose, I just am trying to figure out what's going on.)
