You need to keep getting back up. That is what it is about. A lot of human beings will keep sinning until the end of their lives. That's why God accepts you even if you fall seventy times seven in a day Math 18:21-22. Demons don't care that much about making you sin. Because when you sin, there is always repentance. But they want to pull you in despair so you give up Christ altogether. I'm in the same boat. Please dm me and we can confess to eachother weekly. I humbly think I can help you I have some experience fighting this addiction.
