Rich4j, your daughter is going to be fine, it's you I'm more worried about. It's key for your to keep your composure when D is around you. Little eyes are watching. Do whatever it takes to get yourself to a better place so you can be the guiding light to your D. The best thing that happened from my separation is the alone time I get with my daughter, I didn't have as much of that when we were living all together. This time spent alone with my D is priceless and one of the gifts of my separation.
I've made friends with other single parents with kids or my friends who have kids and we go for play dates on the weekends. This has helped with the loneliness.
You can meet people online. I went to a single parent meet site, though it was a dating site I mentioned in my profile that I was just looking for friendship at this point and kids playdates. (It's important to heal before dating so careful not to get drawn into dating until you ready)
