Sean...
Really sorry to hear about all of this ...
Possibly I can help. I am NOT a "Bible Thumper" !!! _ I am probably the worst evangelist in the world... but even so this mAY help.
I have been diagnosed with some rather severe problems, four (4) varieties of cancer (myeloma, lymphoma, bone, and prostate); total renal faiure; at one point, congestive heart failure; severe anemia ---
The day I learned of that diagnosis was the blackest I've ever experienced. I kept thinking "I am going to die from all this." - a thought that would not leave me.
Until... something else - another thought - "took over": simply "Maybe not."
I realized that no one could predict what would happen - I might as well die in an automobile accident, or get hit by a meteorite in the parking lot.
When? No one could predict that either... the doctors can't and WONT try.
So - I don't know how, or when. Realizing that, nothing had changed.
It would be up to what I call a Supreme power, "God".
What will happen, WILL happen, according to God's will, according to God's plan, and in God's time.
Some time later, I died during a normally routine procedure, a heart biopsy, where a catheter was inserted into my heart, through a blood vessel in my thigh; the purpose being to obtain a sample of heart tissue. Unfortunately the catheter pierced a ventricular wall, my chest filled with blood, and my heart stopped. They had to crack my chest, drain, and repair the damage - and restart my heart.
Four days later, I was discharged from the hospital and returned home.
Now - I feel GOOD! Probably much better than I did before all this trouble began. I' too had some severe back problems (herniated 4th and 5th Lumbar
vertibrae), which seemed to "go away" with the regulation of my blood electrolytes.
The only advice I can give is to try to listen to you body. If something hurts (you'll have to disover your own "alarm' levels), give it rest. Be kind to to yourself. Realize that there are many working very hard (if it was not for one doctor who would not accept the decision to "give up" on me ...), and there are many praying for you ... including me.
