Struggling to get past my miscarriage

Last week I miscarried at 9 weeks and I don't even know how to get myself back to work or back to normality.

My mood is all over the place. One second I think I'm fine and then all the sudden all I can do is cry.

All I can think about is getting pregnant again, suddenly I miss getting morning sickness and having sore boobs.

Plus I feel like suddenly everyone I know is pregnant and I feel so jealous.

I don't know how people do this. Before this I feel like people aren't given a accurate representation of what a miscarriage is like. I've been through a lot in my life but this has broken my heart more then I thought was possible.

How long did it take people to get pregnant again after?
