You know, one downside to a prop-bet for hands is that it makes you think you should play when you're really not in the right condition to do so. Sounds like your head really isnt where it should be, but you're trying to grind anyway. Dont do that man.
Put people on ranges, review later whether they were really valid ranges or wishful thinking ones. If they were valid and you ran into the top of their range, well that happens. It sucks, but it happens and we just need to accept it.
Take a night off, go watch a movie or hang out with friends or something.
