You have no idea whar depression and deperation is until you wish you have E coli and cruing because you don't.
I can understand I think.
My Mom and Brother have had a bunch of strange illnesses they haven't been able to confirm at all. My Mom has gone through just about every test but they can't figure out why she gets sudden life threatening blood infections.
As for me, my parents would punish me when I was a kid if they took me to the hospital and they found out I wasn't sick, so when I did feel bad enough to go I would always hope that I actually was.
But, anyway, I don't know how to help you not feel tired anymore... But maybe having some fun would help? I'm free right now and I have a collab idea that would be a lot of fun. And of course, we do it at your pace.
