Dang, Charlie... no idea. :(
Many of us here can empathize with your employment issues.
This physical challenge though, that is a pill.
Stress is what we tell ourselves about the situation we're in at that time. Healing is also a lot about our mental state...
Go find that special place that allows you to renew your spirit and mind...
I too share the insurance and health challenges that go with bad jobs or none at all, but thankfully, I'm not facing whatever malise you are being challenged with right now.
All I can share is that small still voice saying that this is your time to "let go, Let God" and Let HIM be in charge.
When we reach the end of our rope, it's time to tie a prayer knot and hang on for dear life.
You are in our prayers for a good diagnosis, a better prognosis and that you find the inner strength to Trust in Him who promises never to fail us, if we but Believe....
Keep the Son in your eyes, brother.
