I get angry very frequently on any issue which does not occur according to me.to any person I shout .I feel my body is shaking and my blood vessels will burst when I feel angry .This happens frequently to me. also I feel sometimes to cry and I cry a lot.if I think a lot about my plm  then I can't sleep over night.sometimes I feel that time is passing and I have done nothing and I am useless and worthless in this world.i can't concentrate on my studies also due to this.am I getting mad ?
