I feel like im gonna go crazy...

I'm 33w pregnant and a ftm. I had to get a restraining order filed last week against my baby's father because of threats he made and abuse. Which they have yet to serve him so he's been blowing up my phone. I texted telling him there is a restraining order. I'm afraid of what he'll do. Dealing with figuring everything out for my baby, working full time and everything else is so stressful. Before he left he never bought or did anything for us so now I'm on my own. Drugs are what's important to him now. Sorry for the long post, needed to vent.
