Hair puller

Hi, soooo I have a bad habit of pulling my hair out from the root and now I have a huge bald spot on the left side of my head that is super hard to cover up. I big chopped in April 2012 and I have about 4 inches of growth. My bald spot is growing back but I can't wear my fro or hardly any other style other that a puff because I have a hole in my fro smh. I was considering doing another big chop but I am undecided. I NEED HELP!!
