Is it likely I'll develop disorders when I'm much older?

I have a terrible family background with crazy people. My maternal great-grandmother's father was a criminal and crazy. My great-grandmother (mom's grandma) used to drown puppies during her youthful years and later turned out to be a narcissist and crazy. My grandma turned out normal (though, traumatized from how her mother was) but my own mother developed some narcissistic traits. My mom nearly ruined my father's life during an ugly divorce. She tried to have with him falsely charged with sexual assault. Luckily it was recorded about her accepting it's false but wants to ruin him.

I've heard mental disorder are inheritated. It's already bad enough that I physically looked like mom. I'm scared of becoming like them or turning out crazy or emotionally unstable. Is it likely I'll develop disorder when I'm much older?

I hate what my mom tried doing to my dad. I testified against her. I'm trying to run away from this horrible family background.

I can't find it in me to hurt animals, to ruin people's lives, to defame a guy for something serious, nor any of those horrible things. I'm innocent in all this but yet I'm scared that this thing is in my genes and I might changed when I'm much older. I'm scared of becoming what I hate.

It even haunts me in my dreams someone. I had a terrible dream that I was doing bad things and had an evil smile. Then I woke up screaming.
