Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. These are purely negative thoughts. When you can interact with your friends at college, you are doing well in the terms of making friends and enjoying with them. No worries on that aspect. When at home, you are keeping away from other family members, or other family members are keeping you away. Whatever the case may be, you need to change accordingly. No self pity. Feeling alone, in one place, and not alone in another place. - this is no symptom of any mental disorder. This is pure negative thinking. Forget it. If you require more of my help in this aspect, Please post a direct question to me in this URL. http://goo.gl/aYW2pR. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques. Hope this answers your query. Available for further clarifications. Good luck.
