It often happens that a man develops a deeper love and friendship with his pet cat or dog than he does with most of the other humans in his life.
Shaytan will tell you that you’re not worthy, so give up. But his traps are based on lies. When was any of it because of *your* worth? It was all because of His mercy, His generosity, His love of giving, and forgiving. And those qualities don’t change because you’re messing up. Just seek them. Call Him by His mercy, not by your deeds.
