I am feeling extremely depressed from last 6months , one or other thoughts always prevail in my mind like if I don't do this than i will suffer from sexual problems and sometimes also if the stress is too big I suffer from erectile dysfunction also I have thoughts about a prerson that he will hurt me and some things like that I am lisble to do every stupid task like saying sorry unnecessarily . Also I loose self confidence in public areas like mobie theatre. what should I do??
