Pregnant and alone

I recently had to put a restraining order on my ex ( witch it my baby's dad) was not the easy thing for me to do because we both have little girls and they love each other but it was the safest thing to do since he has a history of abuse and has put his hands on me in the past knowing that I'm pregnant I don't know how I'm going to do this all on my own I'm trying to stay strong I work two jobs and doubles twice a week it's been very stressful.
