In that case, I agree with continuing to be there for her as much as you can but just try not to take anything she says toward you personally. It’s likely all a product of her emotional state and she probably wouldn’t be doing or saying those things if she was in a better frame of mind or feeling happier. Even though it’s unfair to you for her to treat you that way, the reason for it is a little out of her control right now because it seems she isn’t equipped to control or deal with those emotions that are causing her to be so upset/aggressive. So I feel like being understanding of that will help you deal with it, too, because it will feel less like a personal attack. You know what I mean?

Another thing that could help is literally Googling “ways to cope with difficult people” and reading up on different things until you find a strategy that you feel will work well for you. It’s never fun to be in that kind of situation, but there are so many different things you can do to help you through it, and remaining patient, kind, and empathetic with your mom even when she’s acting miserably may actually help her a lot since at least she will know she has someone in her corner. Just be mindful of your own mental health and it’s always okay to set boundaries where you need to.
