Surprise

Lord,i really need help

It's exactly three weeks to finals,my notes are increasing by day and i can't remember the last time i had decent sleep. Coffee has become my crash diet,can't operate without it. There's still practicals i have to be ready for. At this rate am afraid my system will crash,but what else can i do. I want to move to the next class and while am at it i need good grades. Part of me feels that there's something missing. I don't know what and i hope time tells. That's just my life at the moment and if someone would send some help my way, i'd be more than glad to take it.
