I have been on vacation, and haven't played in about a week, and i just tried to play, after 2 nights of no sleep and full school days+work... and I suck ***. My fingers are doing the wrong things.. I am mentally retarded when reading music (really slow takes me like 5 seconds to be like OH! thats an E!) my hands have no energy in them and they are like confused almost?? Do you think this is lack of sleep and I will get over this or am I going to be stuck with playing crap music..? before my trip I could site read very fast and smoothly with few errors... and my fingers seemed to know where to go. Is this permanent?? guitar was the only thing i was learning well and picking up on...and now i feel like im in a cloud.. is this tiredness or just i suck?
