tl;dr: How can you demonstrate higher value if you have none?

Hey all. How's it going?

Here is some back ground info. I'm a single father recovering from a nasty divorce. It was initiated about 6 months ago and left me and my daughter homeless. We are just now recovering.

Ex wife took the house, and sold my car. We live in transitional housing for homeless veterans now. I have no job, no income, no social life. My daughter is my full time job. I have to wait to get a job until I can find childcare for her.

My situation is fucked to say the least. My marriage turned me into a beta bitch. I have no idea how to recover. My ex had been cheating on me for a while before the divorce, my self confidence is nonexistent now. She took all I had.

Is it just not feasible for me to try dating? My days are spent taking care of my daughter. She's amazing, my whole world. However, when she is with her Mom on alternating weekends, I have nothing to do. I clean and mope around my house. I have no idea how to fix myself. I was raised to be a "good guy" but that led to my wife leaving.

I've learned that a good guy gets shit on. But how do I change?

I finally got my stuff back from my ex, so I have more than three pairs of clothes now. However, I don't even have money for a haircut, so my ability to look good is diminished. I'm not unattractive, in fact I'm downright sexy according to the numerous gays guys online. That isn't enough though. Without value I have nothing. Am I shit out of luck until we get back on our feet?
