Pookie,
In your hands, I'm certain your daughter is getting the best care she can.
no shortage of single mothers exists in this day and age. You're not alone, and you don't have to be. Try to see if there is a way to meet up with others and have some social support - where you can bring your child and socialize. It might be as simple as befriending women in the grocery store, or perhaps organizing a potluck (they often have bulletain boards in local grocers for posting) where you could meet other single mothers and befriend them. I know it probably sounds crazy and unlikely, but there are many others out there feeling exactly what you're feeling. If not for this forum being created, we would not be here. We would not be in contact. Someone took that step created a way for us to correspond.
What do you want in your life? What would make it better?
