Miscarriages are just so hard. People don't get it unless they have been through it themselves. They don't want to talk about it, or don't know how, and they expect you to be over it so quickly. I'm only 6 weeks out, and people have said things like, "I'm so glad you're on the other side of it now." It makes you feel silly for not being over it, AND it makes you less able to talk to people who you normally reach out to for support.
Unless you've been through it, you don't understand how hard the milestones are... we would have been finding out if it's a boy or a girl, the baby would have been kicking by now, would have been having a baby shower, and then the huge one... the baby would be here! That's a big deal. Go easy on yourself.
