I feel so alone and I feel like God is upset with me

I have been feeling depressed lately. I feel like God is upset with me because every time I ask him for forgiveness and help to deliver me from the grip of alcohol and drugs, I keep going back to it. I know he loves me and every day his grace is made new but sometimes it is hard to believe that. I’m praying to Him to help me see myself the way he does. Please pray for me. I’m trying to go sober.
