PPD or something much worse?

So I belong to a pregnancy support group on Facebook and this girl made a post in regards to her daughter. When I read the first part I immediately thought she had PPD and felt bad until I read on. I feel like her thoughts and feelings go way beyond PPD and I really fear for her daughter’s safety. She made a separate post that’s stated she also didn’t pick up her daughter for 2 whole days besides to feed her and change her but that post got deleted. Here is the post.

What do you think? Is this a severe case of PPD or something much worse?

Edit: I figured it would be easier to make an edit instead of telling each individual person. Yes a lot of people on the Facebook group has tried contacting her and her boyfriend both. I have no idea if any of them got through to either of them as the post got deleted shortly after.

UPDATE!: so one of the ladies on the page posted in the group screenshots of her conversation with the girl and I’ve decided not to post them. She told the girl that she may have PPD and that she really should reach out to her dr and allow someone to help with the baby so something bad didn’t happen. The girl responded with very nasty comments and called this girl a bunch of names as well. So I definitely don’t think she has PPD and she has other issues that need tending to. But the lady said she also spoke to the boyfriend and he has primary care of the baby now.

Another update: the lady told us that her boyfriend said she went completely mad and refused to get help and threatened to kill her self. She has also deleted her Facebook as well.
