You have to focus more when you are doing it and ignore all the thoughts that may come afterwards. You are opening the door for Satan to destroy your life through OCD as you are choosing to be like this!

I am faced with alot of doubt in my everyday life. Even in simple things like like sayimg Bismillah before eating. Once I have said it I have doubt on whether my pronunciation was incorrect or a sometimes a few minutes into the meal I feel doubt that I might not even have said it altogether. This is just one example. How do I deal with this constant feeling of doubt in my life.
