My husband told me my brain is fucked.

Just kind of a vent. My mom is pretty much a textbook narcissist and we spent the weekend with her. My husband was paying attention to her behavior and mine, watching the usual patterns, observing quietly. This morning, she called me to yell at me about how she doesn't know how her headlights work in her car. She's had the car for three years, I gave it to her (I always give her my cars when I get a new one). She said, "I NEVER KNOW WHEN MY HEADLIGHTS ARE ON AND SOMETIMES I DRIVE AT NIGHT AND DON'T REALIZE THEY'RE OFF AND I'M DRIVING IN THE DARK! DON'T TOUCH MY SWITCH!!!!!" It's a simple switch, clearly labeled, it isn't a new car by any means, not confusing at all. She's in her 60's. In addition to that, my husband has been working on both of our cars all weekend, doing maintenance. She needs tie rod ends, and he does everything for free, she doesn't even pay for parts... This was probably the smallest of things that happened this weekend, I just thought this one was a little funny. When we got off the phone, I laughed about how it's my fault that she doesn't understand headlights. He didn't laugh. Instead, he got kind of serious and said, "Your brain is just *fucked* from being raised by that. You're not annoying, everything is not your fault, you didn't do anything wrong." He's not wrong... But ouch. Now, I can't stop thinking about all the ways my brain is fucked. I'm tired.
