Dealing with loss.

Cece
How do I go back to feeling happy? How can I just be okay with not being pregnant anymore? Everyone keeps telling me things happen for a reason. What reason ? What is the purpose of the physical and emotional pain! My heart hurts. I'm sad and disappointed in myself . I try not blame myself , but I can't stop being angry with myself. My fiancé wants to keep trying , but I don't see what the point is anymore. 
I've never felt like this before, and I'm afraid it's going to consume me. I have no one to talk to. My friends are acting like it doesn't exist , like this hasn't happened or something. I'm going through feelings I can't process , and I'm scared.
