i used to hate God myself but then I realized I was the cause of my own problems and deflecting everything on God. it wasnt until i hit rock bottom that I began to realize how wrong I was. you need to accept that you made mistakes in your life and that God expects better from you. If you accuse God of doing evil you are in fact blaspheming him which is what i did and regret so dont fall into the same hole i did. First repent of your sin and then ask for mercy and understanding so that he may let you know what is causing your trouble. then you can work from there. the Lord heals the brokenhearted and binds their wounds. I recommend doing something like fasting and prayer.
