No energy!

Ever since we got home from our trip I have just not been motivated. I don't know what it is. I just can't get the energy I guess I should really say, to workout. Nothing! Until one of my 1st graders ask me "Do you have a baby in your stomach? Because you look like you are pregnant like my momma." I guess it is time to kick my butt and get back in the groove. I don't know what has gotten into me or what I can do. I just can't get out of this funk. Weigh in is tomorrow and I know I will of gained. I sure hope this, whatever it is, leaves me soon. I know you are probably thinking she is just being lazy and if she really wanted to diet she would. Yes this is true, but honestly not true at the same time. I just can't explain it. I am exhausted. I have been going to bed early. I am hungry not stop. I have no energy. I just can't explain it. Any suggestions? I just need a boost!
