what did it taketo be a good single mom?

Im just wondering.

Uh, taking care of your child.

Exactly same things that it takes to be a good parent generally....

I'm not sure why marital status makes a difference.

There's no handbook or secret trick. Just try. Do the best you can. Get help when you need it.

Every last thread of sanity I had.

Swallow your pride and ask for help when you need it. I don't know, I haven't really changed as a mother since I got divorce. Just takes more organization and patience than when I was married. Definitely learn to not sweat the small stuff!
