whenever I have to present myself in front of people like speaking or answering questions, I start to tremble. My whole body starts to tremble that even after completing the task I can't stand still. I feel very hot like my face is burning. That's why I avoid speaking in front of people. I just worry about my incompetency all the time. I feel worthless and hopeless all the time. I haven't been truly happy for a long time. I am even afraid of happiness. I can't concentrate on my studies. I just want to run away from all the worries. That's why I distract myself by listening to music or watching mobile all the time. I know my future will be ruined by my actions but I just can't face the reality. I really don't want to live. But I don't want to die also.
