Hello aspie_science_nerd: The Skeezyks would like to tell you that he has been where you are. I don't know how seriously you are banging your head. But, if you are seriously & repeatedly doing this... please be forewarned that it can cause some serious & permanent injuries you may not have considered including tinnitus (ringing in the ears) & eye-related problems such as detached retinas.

Something is driving you to slap yourself & bang your head. You need to try to figure out what this is... probably with the help of a therapist. But if you cannot do this, or if it doesn't help, then you should really consider talking with your psychiatrist (assuming you have one) about psych med's you could take that would help. Based on my experience, I would have to say there aren't any magic solutions here. I no longer do this. But it is through sheer force of will... & fear of additional injury. I still feel the urge every day. Please reach out, in real life, for help.
