Why Can't I Move Up?

[mj12]

just force urself to move up you may lose at first but u need to get accustomed to the bigger bets. Ive found mself thinking about stuff like "o man thats a big bet to call with 2nd pair i dont wanna risk it" when obviously your decision should be on pot odds, hand reading and proper strategy. Until you become comfortable with the blinds you will think of them as $5,10$ etc instead of 1bb.
Solution? just play conservative for a week or 2

Dude, at least you are doing something at 0.5/1. My history is similar to yours, I started at pennies with 20 bucks and grew it up a lot, always using a good bankroll management.
But I've been stucked on NL50 for the last 4/5 months. Winning 1500-2300 USD per month on those playing 30-35 hours per week, I have bankroll to be playing higher than NL100, but EVERYTIME I tried NL100 I got kinda busted and went back to NL50.
Im down 3.35PTBB/100 after 27K hands at NL100. Pretty sad and I dont know what to do. I'll just keep building a larger and larger bankroll and I'll try it again soon.
