Head banging/ self injury

I have the exact same issue, my earliest memory of when I started head banging would have been around 8/9 I would get frustrated with video games I would literally over time destroy my controller by hitting my forehead. From that its spiraled into heaps of other things such as overwhelming emotions, failing an exam and many other reasons. 

I've seen five psychologist all to no help at all.

Ive tried searching forehead scars from head banging on YouTube Google trying different combinations all comes up with autistic children which is no help. 

The scarring on my forehead from the 20 years of hitting my head is horrible, it's embarrassing I wish I could upload a photo and attach to this comment to show the severity as words only have an linguistic expression of reality.

How long have you head banged for ?

I have a similar response, when I cannot cope with a situation any more, the pain is like a reset switch. I used to thump the sides of my head or headbutt door frames. I found that changing to something that does not bruise or cause headaches was useful for me. I now slap the sides of my head or face, it still works as a reset, but causes no actual harm.

You could be experiencing a low-grade on going / non-stop state of stress which escalates to a profound intensity. 

For instance, what is your home environment like and would you be able or even interested in making suitable changes/accommodations for your own needs? 

Hi. Adults do to. ADHD can be this symptom. It is channelling your anger and frustration out because you have no other outlet. Please seek GP and NHS advice. Best wishes.
