Tips for a Partnerless Pregnancy?

I made the difficult decision to leave the father of my unborn (9 weeks pregnant) baby.. it was a necessary decision for mine and my baby's safety.
I'm now faced with going through the remainder of this pregnancy totally alone, and as this is my first baby, it is creating quite a bit of anxiety.
My family is supportive, but a little judgemental because my pregnancy was unplanned (I am 25 years old and more than capable of caring for a baby).
Anyone have any tips on going at it solo?
