Falling apart in front of a teacher?

okay so im 14 and i suffer from panic attacks so i know what your going through with the anxiety. i'd say your emotional because of hormones i was exactly the same this year and dealing with other problems to could stress you right out. i cant answer the self harm because ive never gone through that but feeling so sad and crying isnt as bad as you think **** what people think just do what youve got to do, explain to the teachers that your having a **** time and everything is getting on top of you they should cut you some slack then x
