I'm so grateful I don't have siblings
As the title infers, I'm an only child. My mom suffered multiple miscarriages after having me and stopped trying because it was too hard on her.
my dad is the narcissistic parent, and I was essentially brainwashed by him for my entire childhood, not to mention the constant emotional/mental abuse. as a kid, I wanted siblings really badly because I was extremely lonely and isolated, and the few friends I did have all had siblings. I learned about sibling relationships through my friends ... I never admitted it to myself, but I also wanted a witness to what my dad was doing to me, because I was convinced nobody would listen, that there was something wrong with me that made people not want to listen to me.
looking back on it now, I am eternally grateful I don't have siblings. no child should have to go through what I went through, so I'm glad it was just me. not to mention having siblings would've made things worse, especially if I had a brother - my dad always said he didn't care what gender I was so long as I was healthy when I was born, and even though I was a tomboy and enjoyed doing the things he did (hiking, snowmobiling, camping, fishing, etc.), in retrospect, I know he would've preferred a boy because a boy might've been easier to manipulate. he always got along with his friends' sons better than he did with me, and I always wondered what they had that I didn't.
what sucks is that I was a "daddy's girl", and that unconditional love and adoration I had for him wasn't reciprocated.
