Struggling with health / figuring out what's wrong

Hi everyone,

I am currently in the process of figuring out what is going on with my body and struggling mentally because of it.

I have Hashimoto's thyroiditis and suspect that I might have Celiac disease as well (apparently they are best buddies), because something feels completely off.

My symptoms are varied and random, but one of the worst for me is the brain fog and debilitating fatigue I experience several times a day after meals. Like, not tired because I ate too much but tired as in I absolutely HAVE to lie down and wait for it to pass, and even a street full of car traffic seems like a fantastic place to close my eyes and rest. I just can't function properly at the moment.

I'm waiting for my blood test results as well as an endoscopy, and by now it's only two more weeks to go, but I just don't know what to do with myself until then anymore. I constantly feel anxious and/or depressed and I'm super disappointed in myself that I fell out of any workout schedule even though I usually love it and it gives me so much good energy.

Most of all I'm worried that in two weeks they can't even tell me what it is and that I'll have to continue running to doctors and getting useless answers. I just want to feel energetic and like myself again.

Has anyone been in a similar situation?? I'm really grateful for any hints on how to deal with this strange time in my life.
