Not to be resentful

So, I've decided to stay away from Pinterest and Facebook for a while. We found out at the end of November that we lost the baby. We knew it was a possibility, but honestly, when you get to 12 weeks, you think you're safe. We had an ultrasound the week before and everything looked fine. We went in the next week for the 12 week scan and find out what we were going to have (she's usually right, even that early) and found out.
I thought I had been doing ok with everything. I have my moments. I am so lucky, because I already do have two kids. But I want to know who this little person would have been. I want to know it's personality. What it's face would look like. I especially would like to know if it was a boy or girl.
Anyway, back to the point of this post... I have bunch of friends that are pregnant right now. As excited as I am for them, it hurts my heart to see all of their updates and pictures or their adorable pins on Pinterest. I definitely don't want to delete them or hide their feed. I think staying away for a while will help.
