While your name might be "small minnow" I have to think that you have been a huge support to your friend. People handle illness & other life difficulties in various ways. Sounds like your friend is a private person & your on-line relationship is a great support to him while still maintaining his privacy. At 7 weeks of radiation my husband Bob was at his worst in terms of pain & meds not providing much relief. A month after radiation he started feeling better & the side effects began to decrease. Hang in there, pat yourself on the back for being a good friend to someone in need. I hope your buddy will be in contact soon.
