feeling lonely

I haven't been using this app for a while. I thought it might help because I'm not stressing over everything being perfect. But I haven't had any success in that either. 
I feel like I'm the only one that can't have a baby. I've had so many dreams of me having children and being so happy having a baby but then I wake up and I become really depressed that it's not happening.
I know pity party on me. I wish I had someone to talk to but in a world of  billions I feel I am the only one.
