Sounds you have really been doing all you could to preserve your health. That is extremely important. Even if your ailments are progressing, I hope you can find comfort that you have been doing your part to avoid deconditioning.
Some of my worst times were early on in my illness when I felt totally helpless. Now, even though I am getting worse depsite my best efforts, it's the fact that I am making the effort to stay well that helps me cope. Because I can focus on the aquacise, healthy diet and lifestyle, I can let go of most of the frustrations of chronic disease and leave them to a higher power.
I must mention that I think you are wise to make the decision not to drive. It is a big blow to independence to do so, but you are being considerate of your own and others' safety. I do not allow myself to drive more than 45 minutes continuously because I cannot safely remain alert for long periods of time.
I hope what I said above made sense. I wish I had more help to give you. Please continue to be the best you that you can be.
