Mother is toxic?

I feel like I’m realizing that my mom is toxic. She helps out a lot with my five month old and I’m so grateful for that and have told her many many times. Well I need her help tomorrow and she said she would take her for the night since last weekend. Well today she told me it seems like I just can’t get rid of my child fast enough bc I asked her what time she is coming and all that. I’m a planner so I just wanted to know the details. Then she proceeded to call me selfish and that she gets I just can’t handle my child. I’m dealing with PPD and anxiety so it just makes me feel like a pos. And before all of this they day I went to try on wedding dresses she told me she doesn’t want me to get married and wasn’t excited to shop with me.
