Sounds to me like you should make a Doctors Appt. And let him run some tests to see if he/she can determine the problem. That could be caused from many things and only a Doctor could really tell you what it might be. Make an Appt. As soon as you can !
I agree with Rooster but its too hard to correctly diagnose you on here
Not even a doctor would diagnose what's wrong with you without examining you in person and/or running tests. See your doctor. Asking random people on the internet about medical problems could do you more harm than good.
Maybe you have insomnia, get a blood test maybe?
