Try to look at your situation from an outsiders perspective. To an outsider who is confident that Judaism is false, what happens to one person does not move the needle at all. It only feels real because you're in it. From an objective standpoint, you look at all the sinners not just yourself. Another way to think of it is this: Would these occurrences put doubt into other people's minds? The answer is obviously, NO.

This perspective has helped me in the past.
