So sorry you're having such a hard time, the not sleeping is torture isn't it.

I remember getting sooo upset, thinking is this how I'm going to be for the rest of my life, I can't stand it, severe headaches for days, swaying when I walked, eyeballs hurt, disorientation...on and on...

I do know when I got upset and so frustrated everything escalated, so I tried to go with the flow so to speak and kept telling myself it's going to take time, your brain is injured so take it slow.

Hope you have some relief soon.
