Unfortunately, I have been there as well. Big hugs go out to you for I know how devastating a loss like this can be.
Take time to heal. Take some time off and mourn the loss. It isn't easy to get through but you can do it. The tears will stop but it takes time.
For what it is worth, many who have miscariages often get pregnant again within a short amount of time. The anxiety is a bit much to deal with after recently losing a child but those I know that have been through it make it through the next time without issue.
Just remember, this wasn't meant to be for some reason. You would not have wanted a child with a lot of problems. You want a healthy baby. Take some deep breaths, let the tears fall, and take one day at a time.
