It is not biblical faith. It is full of shame. Some things do happen quickly, of course. I know of many people who have been instantaneously delivered of their craving for alcohol. I have yet, however, to meet a single person whose family has lived with the chaos of addiction and then has experienced instantaneous deliverance from the effects of these years of dysfunction.
Recovery takes time.
The real damage done by the Apostles of the Quick Christian Fix is the damage done to our capacity for hope. If we insist that our recovery be so rapid that you can see it every day, our capacity for hope will gradually diminish. That kind of hope during recovery comes from the conviction that God is genuinely 'higher' and more powerful than we are, that He pays attention to us, that He is actively involved in the process of changing us - even when it doesn't feel like it. May God grant you the courage and hope you need today to continue the journey. May your roots sink deeply in the soil of his love.
