Check out My Depression Journey. I mention briefly my struggles of how my depression lead to Trichotillomania.
You may have come to this page either from searching Trichotillomania or just have a curiosity for all things medical (such as myself). I am not a medical expert, I am not a psychologist; what I am is a person with real struggles who finally decided to open to others. If I can provide an ounce of help to anyone, why not?
