Feeling depressed

I jus yet went through a missed miscarriage. I was 10 weeks but the baby stopped growing at 7. I had a d and e on 9/11 and did fine with it but have been dealing with overwhelming sadness and crying. I know it's expected and I want to try again but I feel selfish not wanting to go through the trying part again in fear of not getting pregnant or this happening again. And scary enough I fear getting even getting pregnant again will not make me happy. Had anyone ever felt this way?
