flowmom, I understand your exhaustion with waking up early and not eating like you should. I've done much of the same myself. My sleep has been affected by my separation, among other things, and I have not eaten well during our time apart. I also take a generic form of Zoloft (Sertraline) and a dextro-amphetamine for my ADD (which naturally suppresses appetite), so I have those working against me at times, too.
These things have affected my energy level, though I'm certainly not weak (like my grandmother's nutty boyfriend said). However, since I know these things about myself, I take a multivitamin every day. I also have a couple friends who check in with me to find out what I've eaten over the course of a day. I didn't ask them to do this, but I know the questions are coming. I make sure that I eat so that I have a report for them! I have had comments at my workplace about my weight, so I force myself to eat at times so that I don't have to endure further "skinny person" harassment.
On the other hand, sometimes nothing sounds good. I can't think of anything I'd possibly want to eat. Food commercials almost make me feel sick. My stomach growls and rumbles, but there's nothing in the world that I want to eat. I force myself to eat something (and sometimes it's something strange) just for the sake of eating.
Thinking of you, of course! If you were here where I live, people would try to force-feed you. It's part of the southern culture to try to make people eat something. My grandmother, for instance, wouldn't take NO for an answer. I've learned this the hard way. She may have called me "bag of bones" at one point today, and this was AFTER I'd eaten a plate of food and dessert.
