I agree, you seem really low and I would get it looked into fast. Mine is usually around 120/80.
I know about fatigue or the feeling I should say. It is truely distroying my life too. The antidepressants don't work or make it worse. I've had all the blood tests the neuro wanted and last mo I asked for a thyroid too. Yes, it came back fine.
I'm on adderall and it helps a bit some days. Still looking for a solution here. Just wanted to wish you well and let you know you are not alone.
Oh, I did see your meds are supposed to have a possible side of high pressure. No idea there - go to the DR please!
