I'm so sorry for your loss. Your are not alone in this, but it is very difficult to see how life around goes on like normal, when you find yourself in this deep pit of despair that does not seem to have a way out.
Don't push yourself, trying to go back to 'normal'. There is no 'normal' right now, and it will never be the same again - you will have to redefine it for yourself.
Most of all - give yourself time to grieve. Your loss is very recent, everything is still raw, and your hormones are all over the place. Don't try to 'get over it' or 'get on with it', allow yourself to be sad, angry, desperate... Your lost your precious baby, and no one will know how that feels except you. Don't be hard on yourself, do what you need to do. Baking made some excellent suggestions, some of which I have also done in the past to help me come to terms with my miscarriages.
Be kind to yourself, be selfish - this time is the one time where you have every right and reason to just think of yourself.
Do you have anyone IRL to talk to? I know it's a very personal thing, but I found that it really helped me to just be open and tell people around what had happened - and I was absolutely astonished how many had been in the same situation! This happens to so many people, so you are definitely not alone.
Maybe you might want to consider counselling to try and help you deal with the grief?
Little steps right now, one day at a time. The loss will never go away, but you will find that you will start to be able to deal with it, accept it and still enjoy life. I'm sorry I can't tell you when that will be, but it will happen. For now, don't fight the grief. It hurts, it's awful and soul-destroying, and you will have the scars for the rest of your life. But your are not alone.
