That does sound like a lot to handle, but you've been managing so far. People taking shots at your parenting are out of line, I'm sure you're doing the best you can, and in the long run it doesn't matter what they say so long as you do the best you can by your kids.

That was the main thing I wanted to say to you, since I don't know of much practical advice I can give you. Just that support networks are incredibly important. Explain to your doctor how you feel, the father if he's around, any close family who can help you out. There is nothing wrong with needing a little bit of extra help, especially not at a time like this.
