Good luck man. I recently went through the exact same experience. Winning with a crappy winrate, barely moving up, running bad, tilt, spew, dropping stakes, dropping more buy ins. Just keep your head up and sometimes as I am discovering dropping will make you figure out how to actually win correctly instead of barely being break even. Let me know if you ever want to talk poker, sweat micros, or anything like that since I am in the same boat as you.
