Why does my mom not like when I succeed?

Anonymous
I called her to give good news that I returned a used car I recently bought that was having too many problems and was possible flooded car by the problems it had. I told her I bought the same type of car but in way better condition with few miles on it. She instantly got so mad and started calling me stupid and that I'm doing stupid things and why didn't I keep the other car. I told her this car I just bought is great condition plus cost $5k less. She kept trying to talk me down and say I made a mistake. I told her "why are you mad? I'm giving you good news."
She goes on saying "good news?". I got annoyed and told her nevermind bye and just hanged up. Why she has to be a hater? I feel like she's also mad that I didn't need her help at all and did it on my own

How can I not let her affect my emotions? How do I not let her words bother me?
