Am I overreacting?

Mom was upset about how the fridge looked, which I understood but then she started asking how her life would be like if she never had kids. Then got annoyed when I turned away because I got upset and I cry when I'm upset, she asked my brother that question and he said her life would be "good" and she also got weird about that answer. She said she can never speak her mind in this house because we'll always take it some sort of way.

I just don't understand what other way I could've took it, I KNOW what she was implying I'm not stupid, and I tried to not look at her because I KNOW I'll cry like a baby, yet she still wanted me to look at her and got frustrated when she saw my face.

I get that none of us was planned but I don't think I'm wrong for being upset when she asked me that, Wouldn't she be upset if I asked what life would be like with a different mom?

Am I overreacting? I probably am.
