How Can Trichotillomania Be Treated?

I’ve been pulling out my hair and eating it for at least 7 years. I’ve recently found out that the hair you eat doesn’t get digested and can accumulate in your stomach and digestive track and cause serious damage. I‘m seeking psychiatric help but, should I see my physician to check if I have a trichobezoar? I don’t have symptoms of having one that I know of, but my condition is quickly getting worse and the hair eating is practically constant. This has been going on for so long. I’m worried I might be developing one. What should I do?
