HUGS Alicia. Sorry this is late, somehow I missed your post yesterday I hope you're feeling a little better today. Sounds like we're going through a bit of the same thing...so take the advice you gave me and be sure to take care of yourself!!!
Please don't feel bad about falling asleep, it happens and I'm sure your kids understand. I don't have kids, but if I did they'd probably never eat! I fall asleep at the worst times with no warning.
Please hang in there, we're here for you. Hope your doc appointment goes well and they can give you something to help you.
