Dear Welcome to HCM We understand your concerns I went through your details. I can understand you. You are lonely and have no friends. No self esteem or self confidence. Feeling terrible always. These issues happen when you are demotivated. Introspect. What is the reason for your demotivation or do you have any career motivating factor? Your personality seems to introvert, but there should some good aspects to be an introvert. In my opinion, you should consult a psychologist for two or three counseling sessions. The psychologist should be able to understand your problem after analyzing your behavior, attitude and emotions. Then he will advise you what next course you should adapt. Take care.
