should i move back to $25?

[leehrat]

recently i've moved up to $50 6max nl at party. my background is as a successful low-limit player, but i started out at $25 6 max nl and was beating it for 14 ptbb/100. however, i've been doing quite poorly at $50 and i think it's psychological. the betting amounts are just to big for me and i get scared. lags are pushing me around and i know they are but i can't call them down because the $ amounts scare me.

my question for you all is this: should i move back to $25 nl or just try to get over this problem at $50? or should i move back to limit? i do have some unmentionable at party too and i realize that limit poker would give me more unmentionable per month than nl. would i be able to sustain a 12-14 ptbb/100 winrate at the $25? i'm just a poor recent college grad working as a bartender pt and playing online poker so low variance is important to me. thanks!
