Back in Hospital AGAIN!

Have had 2 anxious days getting more and more breathless but fortunately had Plasma Exchanges planned for today so am now in my hospital bed. Oxygen Sats only 83% so I've got here just in time!
Now the wait for the blood results before we can proceed with the exchanges. Also waiting anxiously to see my neuro. I've done this so many times I shouldn't be anxious but the last 10 weeks have been so much better that I feel a little disappointed to be back to square one. Hoping this is just a a hiccup but nervous it will turn into something worse if I'm honest!
