Parents and abortion

I recently told me parents I’m pregnant. I’m 18.

They’ve been on my back about abortion. Yelling. Crying. Telling me I’m ruining my life and making the biggest mistake ever. Me and my boyfriend are so upset. So mentally stuffed.

I never thought this would happen. I’m 10 weeks. I’ve booked the abortion. And I’m a mess. I can’t stop thinking about it. Any advice
