Advice??

I’m still in high school and I’m pregnant from rape. I’m 24 weeks now but my dad wants me to make him pay child support after the baby is born. He’s really bad into drugs and sells them and I really don’t want his drug money and I don’t want the man who raped me supporting me and my child. But I’m scared of what my dad will do if I tell him I’m not asking for child support because he’s always been abusive and he’s an alcoholic and gets mad really easy
