I don't feel so good !

These two days I have been feeling very .. "shaky" ?
I don't know what's wrong but I just feel that EVERYTHING is wrong !
I can't sleep well form my nap, Keep waking up every 15-20 minutes or so.
I can't sleep well last night, I have woke up SO SO many times in between my 6 hours of sleep !

Is something bad going to happen?
Please, I hope not ! >.<
