Re: sigh, I don't know how much more I can handle...
Are they checking your vitamin D levels? I was super exhausted during pregnancy and had really low vitamin D and my midwife said that was a major contributor to the exhaustion and the fact that it was winter didn't help. Do you go outside much? Maybe getting outdoors for a few minutes most days would help a bit, at least emotionally? I know I get extra cranky when I don't go outside for too long. It's so hard being that tired and being sick on top of it, let alone having to care for two other kids. I hope you get some solutions soon. Just keep taking it one day at a time. Or if that's too much, one hour at a time.
