I was asking myself on Monday why I haven’t been following and doing everything I use to do when I’m not depressed, just lethargic, exhausted and existing at a low level of functioning.
So sorry to hear about all of this and I'm glad you are getting excellent care. This is not medical advice but know that in similar situations cardiologists often use "goal-directed care" that includes a large number of medications that have been individually shown to benefit a suboptimally-functioning heart. Most of these meds tend to reduce blood pressure and it is not always clear when the blood pressure reduction is good vs. a little too good. Signs that the blood pressure is too low include worse kidney function, extreme fatigue, trouble thinking, and dizziness upon standing. These can also be signs of poor heart function, which can in of itself cause the low BP, so it's important to discriminate among these -- and that can be accomplished by reducing the meds temporarily and allowing the BP to drift up a bit.
