unbelievably tired ... =\

I don't know what's going on but I'm soo tired ... I've never felt this tired ever since I began my change to a healthier lifestyle. Maybe because I really didn't have a good sleep last night. Fell asleep at 1, woke up before 6. I even waited for my alarm to go off just so I could quickly turn it off. Pretty intense, I know, but I couldn't get some things off my mind. So much that it's frustrating. I can no longer continue this ... I'm too tired to do so.
