Depression after Miscarraige

I suffered a horribly painful and traumatic miscarraige last weekend. Since then I am afraid of the person I am becoming. I am bitter and hate life, I'm angry at God and I feel changed in a negative way. I no longer find joy in anything I once loved. I tried to go back to work and couldn't handle it so I've been home ever since. I don't want to leave the house, I feel safe inside. At the same time I feel completely alone. How long did it take some of you to get your life back? I just want to give up on everything. I'm tired of ppl acting like a MS is nothing and at the same time idk why it's changed me so much. I prayed so hard and all God gave me was more pain. I am broken.
