Ouch, there is nothing to be embarrassed about. It's not your fault. It's a brain chemistry issue. It's nice that your dad cares so much to come and see you. Hopefully you'll enjoy his company and let yourself be taken care of for a little while.

My husband felt the same way you did -- it was painful -- and it took him quite a while before he felt better, but the good news is that it CAN get better (and it WILL get better -- just keep hope alive, ok?).

((( Ouch )))
