Miscarriage.. need to vent

So I said I wouldn't let it get to me and I wouldn't get down but I really can't help it. Currently going through a miscarriage & don't know how to handle it.. I wasn't that far gone but its still had a massive impact on me. One minute I'm fine, then I'm crying, then I'm fine, then I'm crying. I don't know how to feel!! I attempted to go to work yesterday but really couldn't face it today. Any advice?
