Im going to punch the next person who tells me they're praying for me in the mouth

Why do people of that particular religious flair feel the need to let you know theyre praying for you? All I hear is "dont forget I'm a good person" Im going through some of the worst shit a person my age can go through. What makes you think telling me you're praying for me is wanted or appropriate? What's worst is that these people all know i dont subscribe to the those beliefs. After all this, I never will. I've started telling people "whatever helps you feel better" when they say that shit to me. Im just so over it.
