I want to add to this, the thought if quitting crossed my mind at a particularly dark, wet cold time, it left when I realized what a disappointment I would be to everyone including myself if I followed through, I don't even forgive myself for having those thoughts. That was 5 years ago, I laugh now thinking how miserable I was, but I might be crying if I had quit!
You cry anyway, you weenie. Racking sobs that can be heard across the country. You'd think you lost your poncho liner or something.
