We're all pulling for you, Venkat. You're going to get through this and heal. I think in some ways it's worse if you are young and haven't had a lot of physical misery yet.

The mouth stuff is just wretched - I hated having to watch my husband go through it - but he's doing much better now.

Do you like reading? If you like science fiction, you might like Charles Stross' work. It is very engaging, and takes you right into another world. I don't remember where I heard it, but someone described the idea of carrying an emotional and medical burden like it was a physical one. If you hold a weight in your hand, eventually it will seem impossible, and painful to carry. If you can put it down for a bit, and rest, you will be able to pick it up and carry on again. Books, music, meditiation - all let you put the burden down for a time.
