I've been in that situation many times before man. It's probably the worst feeling you can get in poker. I don't play $125 hands though. The most I've ever won before was like $70 with everybody throwing in $10 for chips. You play dollar hands, I'm assuming?
I put $50 online once and got it up to like $200. I thought I was doin pretty sweet and then I lost it all in one hand. I haven't played online poker again lol.
