Hi, From what you have mentioned, you seem to be suffering from an anxiety disorder. Complete diagnosis will need further details but you do have elements of social anxiety which makes you uncomfortable in talking to others. Another element is agoraphobia which is leading to your avoiding going out alone or avoiding crowded places. Anger and irritability is also are part of anxiety disorder. You should consult a psychiatrist for complete evaluation and initiating treatment. You will do well with medications like sertraline or paroxetine. In addition, you should start exercising daily which will help you relax. You can also opt of behavior therapy sessions which will help you relax and be ready to face situations that you are currently avoiding. I do hope I was able to help you out with your query. Best wishes, Dr. Sunil Gupta
