I feel like my sister (younger) was the favorite child. My parents always catered to her, let her do things i wasn't allowed to do, sided with her during arguments, etc. If she hurt me during a fight, it was "me who started it." I always had to hear "be the bigger person!" While my sister could scream and yell at me for not letting her play with/destroy my things. And all that lead to my sister disrespecting me constantly because i couldn't react or respond without her being the one in the right. And this disrespect carried on to my little cousins around her age, as they began disrespecting me too.

Even as I've moved out, my mom will constantly compare me to her. She always says I am way messier than my sister, my sister has more opportunities than me, and such. But I don't even believe that it's true. But hearing it all the time makes me feel like shit.

I just feel like a lot of pwbpd ended up being the forgotten child, the scapegoat. We're always invalidated in order to praise the other child.
