Is it over, or am I just starting up again

Hi. I'm new here. My name is Caylynn and I'm 14 years old. I started picking my scabs at... I think I was 11 or 12 years old. I have no idea how it started, I just started scratching at myself. It started on my stomach and my buttocks (yeah, my butt.). Then I started picking at my arms, legs, feet, thighs, eventually my face. I always hated wearing shorts or sleeveless shirts so I wore pants year round. I told my mom, and she suggested it may be anxiety related because anxiety runs in my family. I stopped for a while, then I started up again, then stopped again. But sometimes I find my hand straying toward an old scar and I see blood and I get those old feelings again. Like enjoyment or a need to pick. I hope I'm not starting up again, because my scars are clearing up and everything. I don't want all that to have been for nothing. And I'm wondering if I had either an acute case or severe, or are all cases the same? I don't feel stressed or anything, it's when my hands aren't doing anything and I'm watching t.v. or in school. I just want to stop.
