Hi,
With out knowing which Dysautonomia you have been diagnosed with there is no answer, just guesses. Dysautonomia covers a range of diseases involving the autonomic nerve. None curable but some symptoms are treatable. I have found with my particular Dysautonomia that stress levels cause mental health issues not the disease itself. If you can get past the shock and horror of having such a disease it can help. I tend to focus on the here and now and not so much on tomorrow, getting through each day as best I can. I have had to accept I'm just along for the ride, in doing so I'm more relaxed and manage to function.
Try the Dysautonomia international website to give yourself some insight.
Cheers
