I just ran across this web site for the first time while searching for information on tyrosine. Somehow I got to your message. I can't tell you the number of times I have had the EXACT same thoughts as you expressed here, down to the cat with weight issues and the mom who likes to buy clothes for you. It sounds like you've been diagnosed with a cause of your exhaustion. I never have been diagnosed with anything but good ol' severe clinical depression. That has been significantly better in the last two years, but I have been exhausted for more than 20 years, each year more so than the last.
I haven't read on in the thread, so I don't know your details yet. I will definitely read it, though, tonight and tomorrow. I wanted to reply right away, though, to tell you I really feel for you. Whatever cause it is for your tiredness, I want you to know there's someone here who believes you and knows that it is very real. Please feel free to write to me ANY time you want to vent. I know what it's like to just want to get it all out.
