How do I make my mother happy?

I was diagnosed with an atypical eating disorder about two years ago. I'm working hard to get completely healthy again and have already made great progress.

Nevertheless, there are a lot of arguments in the family. Small gestures immediately provoke outbursts of anger, and I haven't seen my mother truly happy in a long time. I know that, in some ways, I'm to blame for this, and that hurts the most. She says herself that it's often just small things that she might not have even paid attention to before, but that the "cup is full" because it's been going on for too long, and one wrong word can make it "overflow." In a way, she's right.

I really wish I could make her happy again. Do any of you have any ideas how I could do that?
