I could have written this. So I sympthize. I, also, woud get a check up. It could be a simple as a vitamin defiency. I'm worn out like you. I don't know how I manage to get to work everyday. Thank goodness it's and easy job. I'm pretty sure my fatigue is caused by my medications. I've been like this especially since they put me on a blood thinner. I work, come home and hit the couch until bedtime.
I am a woman and don't have the issues of being transgender. I did take hormone replacement therapy and it really helped, but when I had breast cancer they took me off of it. Of course, I was already so tired from chemo I didn't notice.
Maybe getting out and walking more would help, but if you're like me it's just more than you can handle right now.

Getting older is not any fun, is it.
Hope your feel better soon.
