Teen Pregnancy

I’m really scared. Im pregnant right now but I’m not sure what to do. I’m strongly against abortion. However, if the mother was raped or just mentally unstable to carry to term then I think it’s okay. I don’t want to have a baby right now. The father is a drug addict and it was a drunken mistake. I told him to use a condom but he didn’t and I was ovulating. I’m so scared. I know he won’t be a good father and I’m just starting college. Mentally I think I could do it but I would be judge by my family and others around me. If I abort i’m pretty sure my parents would disown me. Honestly. i’m just very confused and scared about the whole situation. What do i do???
