Not today but yesterday I came back from 5 day rehabilitation. I feel a little better already, and supposedly I can get back to full health in 8 months. It just requires a lot of exercises and some adjustments in daily life.
Here's to hoping you get fully active asap. I had relatives who went through such after major illnesses/etc and know how bad it can leave some and how not all make it through, so here's to hoping yours goes well and you feel much better soon. :)
