I just found this and it brought me to tears

I was sitting on the couch...picking my scalp ofcourse and looking for scabs that i could pull out and eat. I had enough. So i googled it and this was the first page that i clicked on. I immediately gasped when i read the first post and I knew that I wasnt the only one. I read that all of these people feel the same as me. Completely anxious and fighting the urge to put my fingers in my hair and pick and eat. I first read that all of of basically had something traumatic happen to them in their life or have some sort of a diagnosed mental illness. i seem to suffer from both. I am 22 years old and I was diagnosed with depression when I was 19. I Have been taking prozac since then upping my dosage every time i go to get evaluated. I am now at 80mg a day. My father was also a severe alcoholic. There were nights when I would have to beg him not to leave the house, only for him to turn and go to the bar anyways. Needless to say that lasted all throughout my life and it has deeply hurt me. I need to know if someone feels like me because I am shaken right now. When I am anxious at all I begin to itch. Everywhere and anywhere. In highschool i got terrible soars on my legs from me scratching to the point my legs would have to scale over. THANK JESUS that i got past that but now I am a full-blown scalp picker and eater. I also seriously lack pleasure during sex never reaching orgasm.
