How can I embrace being a single mother?

My daughter is 16 months old, and her father and I just split up. For the time being, we’re still living together, but I’m hoping to get my own place soon. I still love him, though, and I’m terrified of going out and doing this on my own. I make too much money for any assistance but not enough to really live comfortably on one income. I think I’m just looking for advice on how to make this easier. I’m also feeling really guilty because my baby girl loves her daddy, and I know it will be hard not having both of us around anymore. It just sucks, and he doesn’t want to try to make it work anymore.
