Hey everyone, I am a Deist currently. I just spoke over a course of 2 days with 2 christians about how they are using fear mongering by saying ( If you don't believe, you are going to hell.) They say they are not fear mongering but trying to save me. It is really affecting my health.

 They are trying to "save me" but really they are pushing me further away by basically threatening me with the you don't believe= hell.  kinda down right now don't know what to do .

Pascal's wager is what that's called. Ask them to consider the same for the other religions, they can be just as wrong as you are. Usually garners an excellent reaction. 

On the "affecting my health" thing. I'm sorry if it's hyperbole, but if it isn't then consider growing a backbone mate. If you don't want to argue then don't, tell them the discussion is over. Simple as that. You don't have to listen to bullshit or mince words with people if you don't want to.
