Is it selfish to have kids if you have hereditary illnesses

Explain why or why not in the comments! personally a lot of mental illnesses and some health conditions run in my family. I’m 17 and have both, mental illnesses and also a heart disease. i don’t want my children to suffer however most of my “mental illnesses” are due to trauma i went through as a child. for as long as i can remember i’ve wanted a family of my own. i carried dolls around until i was 12 because i was obsessed with being a mother i never had. A part of me wants to break the generational curses and be a loving mother but another part of me feels like i could never forgive myself if my child suffered the way i did.
