New to forum but not to picking

I have never talked about my picking before. If you met me you would not know about it. I pick my scalp almost all day long and have over a dosen open sores from picking. My favorite time is the morning cause there completely scabbed over at this point. I try to make them bleed as much as possible cause I can pull out dried bits later. I have been doing this for as long as I can remember. I can't go to a salon cause I am ashamed of my gross bloody scalp. I have not had a proper hair cut in ten years. I also eat the scabs I pick. Its horrible but I don't know how to stop.
