Fear and lack of memory. What i spoke?

I was confused in many things in my day to day affairs.for everything I was feared,i was thinking that everybody watching my activities which make me to think inferior infront of everyone and also I couldn't able to do anything properly or clearly , if I do also there is lot of confusion in that work which I can't able to communicate properly to others which I know.sometimes I think whatever I speak goes wrong and y I can't able to handle situation boldly and finish it with confidence at any cost.this makes more depression and anxiety towards my friends and close persons in my life but instead am getting fear and feel inferior towards a normal person who is not so close.and also I can't proof myself correct if am correct also.this makes lack of sleep,confusion,fear which difficult to do things and exhibiting my weakness to others easily & can't able to take decision in clear manner.I have lack memory concentration & lot of distraction where I can't able to remember what I spoke &read
