Dealing with miscarriages

This last year my husband and I have gone through three miscarriages, 15 weeks, 14weeks and then 4 weeks. It's been so hard for me to deal with and it breaks my heart when family members get pregnant and didn't even plan the baby and they are far along. Should I just get over it? I can't seem to. Has anyone else been through something similar? Obviously there are people that say they understand but I don't think they actually understand what it's like to lose three children.
