You are disappointed, but please dont leave God altogether. Why never eating bread again when your long time baker sold you bad products.
Educate yourself and pick your next bakery carefully. And why not baking your bread yourself?
You can figure out things if you realy want to. Pray and ask for understanding while reading different Bible-translations.
Most important thing is, that you dont need a human mediator. Jesus is also YOUR mediator and you can engage in a relation with him, the son of God.
1. Pet. 5:7 is a very valid help.
Find new friends who respect you for who you are.
God bless.
