Ultimate Marvel vs Capcom 3 General

Welp, today was the most depressing day of MvC3 I've had so far. I don't even think I can stand a chance against the lowest computer difficulty at this point. I decide to take a couple days off, and everyone and their mother can suddenly kill me within a minute. I can't pull of combos I used to be able to land easily anymore, I can never hit the right button at the right time, and my fingers seem to wanna rebel. I think I dropped 10% on my liscence board today x_X. it seems like everyone I face is in my head now. Either that, or I'm severely out of practice. Even spending 2 hours in the practice room trying all the moves and combos I could think of didn't work.

tl;dr

I NEED HELLLPP.
