Self canabalizm?
So, ever since i was a kid i been biting and eating my nails. I also chew nd eat up the skin on every one of my fingers to the point they bleed or where i cannot type or hold slighty cold or warm items. also I peel up the skin on my feet the ball of the foot, my toes and the piece where its firm. I chew up my cheeks and lips to the point it hurts to eat. I have tried to stop, but every time i do, i go into some panic mode. I have no idea what the trigger is. Is this normal???
