Oh my gosh. You have just described exactly how I feel right now.
Not only am I beyond fatigued, but yes I am tired of fighting this as well. In fact when I go to my pdoc this week, I am not going to make any med changes b/c that is all I've been doing constantly for over a year and nothing is working. I feel like I am never going to be well.
I too, put on such an act at work and that is draining as well. I do have a lot of stress; my Mom has stage IV lung cancer, so honestly I don't see any light at the end of my tunnel at all.
I want you to know winnie that I am thinking of you (you too Tortoise!) with this awful feeling.
Sending many hugs,
Mogs
