Same, I felt from an early age that my mother didn't like me very much. She was not overly nasty, just a few sarcastic jokes (that I remember) and not spending any quality time with me at all when I was growing up.

It's taken me years to accept, now I just feel sorry for her that she missed out on building a relationship with me, I feel like I'm an interesting and good person (most of the time) so she's missed out. I don't feel like I missed out on her, she does her best, but because of untreated mental health issues, her best is disastrous. That's the kindest way I can put it.
