Having trouble not comparing myself to others

It is so hard for me going on Social Media to see girls that I know have had multiple abortions in college are now pregnant. Or the couples that post "oops look what happened" or "we weren't planning on having a baby"

Then I think about my situation and sometimes wonder what I did wrong to deserve this? I know I didn't actually do anything but it still hurts.

I used to want 4 kids, 2 boys and 2 girls. Then as I got older, I thought 2 would be okay so they'd have a sibling. I always thought I would NEVER consider only having 1 kid. Now with everything, I'm praying with all my heart and soul just to have one. I won't be greedy, one perfect child is all I need.

I don't think I can imagine my future without a child.
