Hi,
The best solution for your problem is making friends. You are telling you don't have much friends. What is the reason?

Do you feel anxious on meeting or talking to strangers?
Do you worry that people may make comments upon you?
Do you fear and avoid-
Eating, Drinking Telephoning in public.
Talking to people in authority.
Acting, performing or giving a talk in front of an audience.
Throwing or attending a party.
Working or writing while being observed.
Urinating in a public bathroom.
Being the center of attention or entering a room when others are already seated.
Expressing a disagreement or disapproval to people you don't know very well.
Looking at people you don’t know very well in the eyes.
Returning goods to a store or Resisting a high pressure salesperson.

So if many of these are the problems you are facing then you need to meet a psychiatrist/ psychologist. Few medicines and more importantly psychotherapy will help you. You will be developing skills to be assertive and to confidently engage in social situations during the therapy sessions.

If there are any other causes for not making friendship, please revert back to us explaining the situations you are facing and I will be happy to help you out.
