First off I agree with Dave that you dont have to prove yourself to anyone. I on the other hand, think you should take some time off. Spend some time with your family. Go fishing and enjoy what God has provided. You have had enough to worry about in the last 4 years and you are about to have a major surgery. I say you just take the time to get well and then consider coming back. There are many on here that will miss you if you chose to not come back. I hope you will consider coming back for the many that enjoy your posts. Please don't give the small minority the victory.
