I have absolutely been there. I've yelled at my kids or told them I can't have them around me. It makes me feel awful, but I've gotten better about telling them that I'm having big emotions and they're hard for me to control; that I need some time with absolute quiet in order to feel better. I've told them that I want to be kind and patient, and that they deserve that, but that I have to be able to calm myself down or get my emotions to cool down before I can do that. Then, I do whatever I have to in order to get the space - my husband is great about taking them out of my space to help me gain peace. We don't do a lot of digital media, but I definitely let them watch Netflix kids when I need quiet and can't send them outside, like when they were your daughter's age (just a couple years ago).

I will say this - I KNOW it's really hard right now. It gets easier the older and more independent they get. Remember, even when you lose your cool, you can always take the time you need to get yourself together, and then go to her and apologize, explain that your reaction was about you, not her - that you love her and you're sorry if you confused her or upset her.

And be forgiving with yourself. As long as you're honest about your limitations and struggles and aim to be loving and kind, don't beat yourself up when you fall short of ideal. It happens to all parents, even those without MI. I think, sometimes, we're more attuned to how we treat our children because we're more aware of our moods & reactions due to therapy, understanding how our brains/chemistry/emotions work, etc.
