Everytime I try to go out -- I come home and crash...even if its for an hour. Huge blasting headache and exhausted. Any suggestions?

If I do drive, its no radio...and locally -- just to keep it short -- 10 mins.

I still can't even tolerate tv without walking away dizzy and my head hurting all at the top. Even 15 mins...and I really want to watch Modern Family tonight!

Why am I not tolerating more yet??
