Has therapy worked for you?? Should I consider it??

I am a life long skin (mostly cuticle) picker, and it never occurred to me that this is not just a habit. After reading several personal stories in the forum, I am strongly thinking that I need to seek further help. Before I do that, I would love to hear stories about therapy, and if it has worked?? What kind of things do you talk about with them?? What conclusions have you come to realize since you have been attending therapy sessions?? I know this is a lot of questions, but I would love as much information as I can get!!
