My Background: I played varsity football for my freshman and sophomore year,( I will be a senior this year) on the last game of the year  I received a brutal hit that was first thought of as a concussion. Almost 2 years later after literal hundreds of appointments it has been classified as a severe brain injury, far surpassing a concussion. Please note, I am not at all actually brain damaged, I am fully able to think and am in complete control. 

Diagnosed mental illness: Although my initial symptoms from the concussion are gone I was left with very severe depression, and debilitating anxiety which has forced me to take online classes. I am currently in treatment for both of those and trying to get better.

Undiagnosed condition: Even though my depression and anxiety has taken over a large part of my life, I do have one other thing that bothers me more than anything and causes me extreme endless pain. 
I constantly grind my jaw. I am not grinding my teeth, but my right jaw bone which causes a awful clicking and extraordinary pain. I can control myself from grinding my jaw at anytime but I feel the need to grind it like someone feels the need to breathe. At first, like everyones assumption it would be OCD. I thought this to be true aswell but I do not share the same characteristics with anything else except my jaw. With the need to do it I also have this weird thing where I see how much pain I can withstand from doing it. I often leave cuts on the upper right corner of my jaw. They are very large cuts that bleed. I need to stop. Please help me.
