Welcome,
Good you found this community of caring people.
So sorry you're suffering with a self-induced head injury.
I guess we all have self-induced something bad in our life, so don't beat up on yourself too much. You're having it hard enough.
I hope you find your way around the board. There's lots of postconcussion syndrome folks here that will offer you their experiences and try to help you with your struggles. They do understand how it is.
Here's a link to our post concussion syndrome :
