I just started highschool and my mom is talking about having another child because her boyfriend doesn't have any and wants to have a baby with him, and my sister had 2 kids aged 10 and 3 my sister no longer talks to my mother over a dispute of her being kicked out. she had her first when I was 6 so I never really had a childhood to grow up and was always jealous or unhappy since I struggled with depression and severe anxiety in 5th grade. My sister is 25 and I'm 15, I honestly don't know what to do because I don't want another sibling cause I want to grow up without having to deal with another responsibility I don't want anything to do with. I just want to be able to be calm and happy and be able to have kids when I'm older but I also feel like with my mother having another it will distance me from her and make me not want to, want to have kids anymore.
