I can relate somewhat. I was the only child, but "good" stories were never told about me. My mom would tell my aunts all the stupid things I did. It might have been within earshot of my cousins because they all thought and to this day, some think I'm still stupid.

My mom would embarras and humiliate me in front of the extended family. She would openly compare my difficiencies (according to her) with the schooling, degrees and titles after my cousins' names.

After my mom passed on, I got in touch with several of my cousins whom I had lost contact with. It didn't last long, because each and every one of them tried to "teach" me, control me or find fault with almost anything I said or did. Shades of my mother. No thanks! For all I know, I'm the sole survivor of that clan. Haven't spoken to any of them in years and it's okay.
