What do you do when God doesn’t come through?

I’ve been in a legal battle the last 5 years that recently reached a verdict and it is not the one that was likely, that I prayed and had faith for or that I was prepared for because I had faith!

Now I’m literally crying on the pages of Isaiah and Psalms. I am essentially grieving in a way and I dont want to deconstruct but I dont know how to lean in at this point. I am bitter towards people in my life, angry at God, confused and I just feel so lost. How do I surrender and keep believing?
