Anger with God is always the result of a conclusion that a perfect God has treated us unjustly and that we have the right or the knowledge to judge God’s ways. We should take our heartfelt anger and pain to the Lord while holding on to the truths we know about Him. He is sovereign, faithful, trustworthy & righteous, and He has not wronged us.
We should talk to God.
God, I’ve been accusing You of things I know nothing about. You are God and Your good plan and Your perfect ways are beyond my comprehension. Someday I may understand, but for now, I will trust You.
