Can't sleep

Sitting here at my computer its 5:27am have to be at work at 4pm and can't sleep. Got off of work at 10pm yesterday and cant sleep my mind has to many thoughts in it.. and not even tired at all took my medication to, that usually really tired..But tomorrow at work i know i will be tired and really can't offered to be late to work at all.. or will have to find a new job that weighs on my mind alot thats all i think about. So I try even harder to be a good employee and do a even better job.
