I'm the exact same way, I shut down, I stop talking, thinking, moving...I say I have to be quite right now.

Everything just gets too much, mind you I can usually feel it coming on. If I don't stop everything it's not pretty, I'll cry and rant and rave then feel worse, can't control it so try to stop it before all that happens.

I have stood in the middle of the living room shouting stop, stop, stop! should know better to shut myself down before it gets to that stage.

I feel I can only be honest ans say that here as most will understand. x

I know exactly what you mean, Hockey. Sometimes I can't seem to sleep in the quiet because I get to overthinking, then I turn on the TV and I actually have to turn my back away from it because it's too bright to look at. The noise without the picture can be annoying but it somehow helps me sleep. I never thought of it as a result of my TBI because I grew up going to sleep with the TV on.
