My 150BB downswing just got a lot worse

It certainly seems like a good run is much less profitable than a bad run is detrimental. I started with $125 on July 1 and played mostly $5 sng's that month. I ended the month at approx $275. Played more $1/2 limit in August, finished that month at approx $475. Moved up to $3/6 limit and ended that month at $650. I wasn't figuring out how many hands I played back then, but calculated hours, which averaged approx 25 per month. During my first 4 days of October, I dropped all the way back down to $150. Everything I could do wrong, I did. Every bad break that could happen, also did. I guess tilt got me, which might explain why we can lose so quickly, but never seem to win at that same accelerated rate. Anyway, now I'm back up to $300, but I took some of the 2+2er's suggestions and am now playing .50/1 limit. I hope your luck turns around soon.
