Oh, I feel for you and your situation. I can only imagine what you are going through.
My husband has migraines and has been unable to leave the house without me for months now. He doesn't drive anymore and is very nervous about being around too many people. He is only 63 but it has taken a hard toll on him.
This is a great forum to seek a sympathetic ear as all of us have some of what you are dealing with.
Are you on any medications? Have you seen a neurologist?
Hang in there! We are here for you.
