Hi, I went through your query and can understand your concern with the troubles you are facing in your life. Facing difficulties on academic front as well as relationships front definitely is bound to make us feel lost. You appear to be short on confidence. From what you have mentioned, it might be possible that you are suffering from some depressive symptoms as well. I would suggest that you consult a psychiatrist for complete evaluation. Anti-depressants like escitalopram will be helpful in tackling the depressive symptoms and increasing self confidence. In addition, you can also opt for cognitive behavior therapy which will focus on learning how to relax as well as help in changing the mal adaptive thought pattern which is leading to current situation. You should also start exercising daily. It will help you relax and feel better. I do hope that I was able to answer your query. Best wishes.
