I have yet to make my first post, but commenting here to say that I have been dealing with something very similar. My primary says it’s anxiety and depression. I’ve dealt with both in the past and while that was such a difficult time in my life, I’d do it again in a heartbeat rather than deal with this agony. I’m convinced that I have the form of POTS that causes high blood pressure/too much adrenaline. Currently awaiting a cardiology appt on May 16th because of heart issues as well. I’m so tired and despite having a great support system, I feel so alone.
