Welcome mountainbikermark! Vent all you like, we've all done it and often it helps. Quitting smoking is easy....I've done it 100 times! Actually it's one of the hardest things I've ever done. Thankfully you only have to succeed once. Many people are happy to cut down to 1/2 a pack or less a day, but I simply don't think I could do that. I'm an all-or-nothing kind of person and I know I'd creep back up to full time smoking if I tried it. Don't beat yourself up about it...unless that helps you to get where you want to be. Sometimes getting mad serves to motivate. Just don't let it make you give up trying.
