Hi Rima, welcome! One thing you will notice is that we all respond differently to everything including meds and whether we can work or not. For me personally I was in your same position, just starting a job I truly loved but had been pushing myself for so long that I knew inside I wouldn't be able to push much longer. It got to the point I couldn't make it a full week at work without calling in sick at least once. For me, my doctor was very concerned about the effects pushing myself so hard had on my body. He felt the constant tachycardia that never let up was bad for my heart and causing a cardiomyopathy. So I did have to quit work for both the effects on my health and because I literally could not push myself anymore. I was physically and mentally drained. So I filed for social security disability and I am still on that and wont ever be working again but not working and being home bound has helped my heart and body in general. There are plenty of people here that can work though with the help of certain meds. And some are able to work more hours than others. It seems to be an individual thing and possibly the cause of your dysautonomia could make a difference as to whether you can work and if your body is affected by pushing yourself. I think once you et your tests back and see your doctor for possible treatments you may know more about your future. Meanwhile, you have lots of support here! I certainly understand what you're going through! It is a loney place, you are right, but it doesn't have to be as lonely because you have friends here that understand
