Triumph Over Phobia (TOP UK) runs a national network of self-help groups to help people with phobia or obsessive compulsive disorder (OCD) to overcome their problems using graded self-exposure. This means learning how to face up to your fears in a very gradual and structured way so that eventually the anxiety should decrease.

Triumph Over Phobia (TOP UK) was started in 1987 with the professional help of Professor I M Marks, MD, FRCPsych of the Institute of Psychiatry, London, by Celia Bonham Christie MBE, MA, who had overcome her fear of flying by following self-exposure instructions from Living with Fear (Marks, I.M., McGraw-Hill).
