Am I wrong?

I moved back in with my parents last year after an abusive relationship that resulted in two under two at 19. My dad passed away almost a month ago. When I first moved away, my children’s dad basically became nonexistent, but decided a couple weeks ago he wants unsupervised time all of a sudden. LOL. So on top of grieving and being traumatized from being so involved in things with his body, I also have to fight for my kids in court. We’re waiting right now to see if he does the evaluation they want him to do (he’s had a week and hasn’t, he has one more week left. Everyone says he won’t but I think he might). Even with everything going on, I’m still trying to move onto a better path with my kids. I’m trying to get them on a better schedule, in daycare, making sure their meals are more balanced, etc. But I get really frustrated because I feel like my family picks on me. I have them alone 24/7 basically, I have since the day they were born essentially. I even for a long time worked overnights so I could work and still be with them 24/7. So I yell sometimes, I get overwhelmed, I don’t do everything the “right way”, I get it. But it feels like any time I do something wrong, my family is right there to give me the 3rd degree about it. Oh you yell at them more lately? Oh, “they deserve better”. Oh you don’t make them sit at the table every meal? “They have to do that at daycare so do it now”. They get into something? “They shouldn’t even be in it in the first place”. I get annoyed because they all have comments but no one ever wants to help with them. Like I’m clearly overwhelmed with them and these things are a result of that. But “oh you’re a mom, you’re supposed to have them 24/7” 😐😐😐 like oh okay. And if I say anything they just say that I take it too personal and their comments are just to help. Well I can’t do EVERYTHING so wtf
