Grasshopper:

That is exactly how I feel and I thought I was the only one. Sometimes I'm pedaling so hard and moving so slow up those hills and I'm so tired and I get scared I'm going to roll right down the hill backwards. Of course, should that happen, I would never be able to control the bike or anything. I'm sure I would crash. Its nice to know someone else feels like I do. Are there many hills where you live/ride?
