Can I make it as a single mother with no support from the father

So I got pregnant during a one night stand and I'm not quite sure who the father is. I was very drunk one night and ended up having unprotected sex with a stranger. I know, bad mistake. So I know I have to deal with deciding to keep the child or not.

I had an abortion once before and it was because I and my ex then weren't ready to have a child at that time. So he convinced me to get an abortion. That experience was so horrible I said to myself that I would never go through it again.

But being pregnant again and not knowing who the father is, makes me really scared. I have told a few people because I was scared and alone but all I got was negativity from them. Telling me I'm ruining my life and how will you tell your child about the father when they ask and such.

After doing some serious thinking, I'm having second thoughts about keeping the child. I'm 7 weeks pregnant and feel like I need to decide soon but can I make it as a single mother with no support from the father? A lot of stuff I'm gonna be thinking about.

Thank you for hearing my story.
