I am currently living in south asia and not able to find an expert easily on cognitive therapy. Is there some good online resource to get info on it.?

International. You might check with the international association for cognitive psychotherapy for referrals: www.The-iacp.Com/ also there is the association for behavioral and cognitive therapies: www.Abct.Org there are some therapists who also may do such therapy via skype sessions, but you would need to be sure of qualifications. Good luck!
