I am the youngest of three technically but I'm also the only child so I am the youngest because my sister was not biologically related to my mom or my dad it was a marriage thing where she came in and my brother was my dad's child I am my mothers only child So I grew up in the household where I got treated like the only and the youngest at the same time And I just want to know like how toxic do you think that is

I don't really know I mean I'm also the youngest child my sister left and I got kicked out so no one really lives in my parents anymore but I don't really know I think my situation is very toxic so
