Scalp picking...

about a month ago, I started to pull my hair out.. one by one till i was bald on either side of my head.. I ended up just shaving my hair completely off cause it just looked so bad and I didnt want to pull anymore.. Shortly after I shaved my head I started to feel and pick and scratch at my scalp, and its just gotten worse, to where I have several sores and scabs and Im constantly feeling them to scratch and pick them off.. even though my scalp gets sore and raw and tender in those spots I still continue to do it.. I want to stop but I cant, I just keep picking scratching and feeling all the time.. Im seeing a therapist, my second appt is this Tuesday, she suggested I wear scarfs on my head and kept my hands busy so I wouldnt be tempted to pick and scratch.. Ive worn a scarf here and there.. but its rather uncomfortable and im not used to the feel of it.. the worst times for me to start picking and scratching at my scalp is at bedtime.. or when im playing my facebook games.. I dont even know why I do it, but I do.. I do have anxiety issues and depression, agoraphobia among a few other things as well... I cant work right now because of these issues... I guess Im hoping that there are others out there like me that I can talk to and relate with, this kinda thing makes a person feel kinda alone and sad.. I dont understand it really.. but Im trying to.. thankyou for reading..
