Was this a nervous breakdown or more of a psychotic break? 10 points?

No, it wasn't a psychotic break, which is a loss of contact with reality and a nervous breakdown is where you loose the ability to function in day to day life.I think it was an anxiety attack.It can cause rapid breathing and shortness of breath., racing heart and chest pain, sweating, a choking feeling,shaking and a feeling like you are loosing control. You are dealing with a lot of issues and I think this episode started as you were crying and worrying about your leg. Anxiety and depression are 2 sides of the same coin .The depression was causing the crying and the anxiety caused the panic attack.
