I have heard abot trichotillomania, but I dont suffer from it. I met a girl with this diagnosis in a rehab. She was very ambitious and smart but failed her exams, she studied law. She had several trauma from her childhood, so thats what problably caused her problems. I?m sorry that you lost all your friends. But they werent really friends. Its not ur fault, that you are ill. Did you work out what the cause of issues is? When did it start?
