Also, it's a mistake to change the form you are playing while moving up. HU is a different beast, and combine that with the dramtically higher stakes, and of course you're going to feel like a fish out of water (pun somewhat intended).

On the other hand, you've basically hit on the hardest part of moving up - once you reach a certain level, the "actual dollars" you are playing before becomes a sticking point, where you feel like you can't push marginally advantages because "that's a lot of money". There's no way around this besides experience and having a BR to cope. Maybe try playing more tables of 1/2 and, when properly rolled (~15k or so), 2/4 to keep it challenging and build your roll faster, and then take some occasional shots.
