Fwiw... Start following BRM better. I understand you believe you should be playing higher stakes and that you are just "stuck", but (1) that might not be the case and (2) even if it is, you can still experience variance lose your roll.

While I won't dis shortstacking at all, because it can be very effective, I would advocate buying in for 100bb. Even if that means playing smaller stakes. Many people can crush 2NL, 5NL in a relatively short time. If you think you should be up at higher limits, then you can use a more aggressive BRM, such as 15-20 buyins for the stakes, but make sure you have the discipline to move down when it's called for.
