Well I didn't mean to add to your weary-ness, trust me. I'm dealing with that myself and am all too aware of how it all wears you down.
Im dragging my ass around lately, totally depleted by this thing and also sleeplessness and a racking cough, among other things. So trust me I get where you're at.
let's hope they can find the right diagnosis that really helps you get better quickly. Good luck with it!!
