I really thought I was fine... Looking for advice

Hi everyone. I apologize in advance, this post is a much needed venting session, but also a cry for help.

It’s almost been 3 weeks since I lost my angel. For the first few days I cried and cried. I felt alone, heartbroken and misunderstood. Then, for a little over a week I was feeling better, despite the dreams about my miscarriage. I was motivated to get healthier and fit, I lost all the weight I gained during the 9 weeks this last pregnancy lasted... But I woke up today and something was different. I was not motivated, or happy. I just feel empty. I can’t stop crying. I can’t eat. I can’t think straight. All I think about is my dead baby and the horrible miscarriage process.. The passing out, the blood, the pain. It keeps playing on repeat in my head and I don’t know how to make it stop. I just want to make it stop... How do I do that?
