Melissa,
The fact that you posted to this forum tells me some things about you. First, you're a survivor - that's what this site is all about. Also, you're interested in preparing for the unknown as are the rest of us here. These are good things for someone in you situation.
Over nine years ago, I married a single mom with two kids. I've listened to many stories of the hardships and difficulties that life threw at her. Her life then wasn't easy, but she found ways to overcome the obstacles that confronted her. She became a much stronger person because of her struggles. She's a survivor, like you. That's part of what attracted me to her.
Stay positive and stay strong. I have a feeling that you and your daughter will be alright. You have each other, and that's a good start.
Steve
