We can think we have all the good reasons in the world to be angry at God, but anger at God is SIN AGAINST GOD and must be gotten rid of.
If you feel anger toward the Lord Jesus Christ, please DO NOT push God away, turn your back on God, run away from God, become bitter toward God, stop believing in God, stop trusting God, etc.
Run to God, put your trust in God, cry out to God, pour out your heart to God, confess your anger and any other sin to God and turn away from it, pray to God, and receive His love, forgiveness, comfort, mercy, grace, kindness, healing, wisdom, direction, encouragement, strength, power, fellowship, and friendship and all He has for you.
“…Have mercy upon me, O God, According to Your lovingkindness; According to the multitude of Your tender mercies, Blot out my transgressions. Wash me thoroughly from my iniquity, And cleanse me from my sin. For I acknowledge my transgressions, And my sin is always before me. Against You, You only, have I sinned, And done this evil in Your sight…blot out all my iniquities. Create in me a clean heart, O God, And renew a steadfast spirit within me.” Psalms 51:1-10 NKJV
