Thanks everyone for your advice, support and engagement. I guess I'm over it. I was super upset at the time, probably because I was really stressed about unrelated things and it was just too much at that moment. I'm so thankful I can come here at those times to just get it out and receive some feedback.

My mom is an extremely difficult person to deal with, but I still love her and want to be a good daughter to her. She was a great parent to me and my brother when we were young. Sometimes I see pictures of her when she was a kid or a teenager and I feel really sad. I understand a lot of the difficulties she's gone through in her life: coming to a new country, raising her family under financial pressure, finding herself without purpose once her kids were older, struggling to find work after being home for so long, etc. She was also someone who took great pride in her good looks and I know how hard it's been for her to see those looks fade in recent years. Every time I interact with her, it's a fine balance (that I often fail at) of protecting myself while still trying to treat her with compassion.

Thanks again everyone! Best wishes to you all.
