I think there’s something wrong with me

My sister was a diagnosed physcopath, and my grandma had mental problems too, so does my mom, but I feel like I show spcialpathic tendencies, I manipulate and use ppl for what I want and all that, I’ve been doing it since I was a baby I don’t remember never not using ppl for what I want and I find it hard to care about ppl I don’t like other ppls emotions it’s weird, trying to get a therapist now that I’m 18 but every time I try to ask how I would do that now that I’m 18 and needa learn and my mom keeps bullying me and apparently me trying to learn what I needa do to be an adult and stable one day stresses her out so it eh
