I agree with brainhi - show your doctor your original post. Just please:
Do see a doctor and try to get some help.
I feel so bad for you. I am also hyper-sensitive and while I have been blessed with many people in my life who understand and empathize, there are also those who criticize me for how I am...as if that helps.
I cannot sleep anymore without earplugs. I also wrap a soft cotton cloth across my eyes so it's very dark. Interestingly, I hung a strand of little red lights over my bed and that, for whatever reason, gives me great comfort. I currently live in a ghetto full of noise and depression and cannot wait for the day, someday, when I move away from this place.
Peace, brother.
