when I was a kid and teenager I had a problem, whenever my father would yell at me I would punish myself by hitting myself in the head... everytime I hit myself in the head I would see a flash in my eyes and I'd be fine... occasionally I would have a headache that went away in hours. I would never have any mental problems after hitting myself and I was never knocked out for more than .10 of a second. am I doomed?

I can recall 10 instances where I hit myselef in the chin and saw flashes in my eyes and stars over a period of 4 years when I was a teenager
