My brain came up with the question, what if you keep suffering from anxiety until a point where you become suicidal and might do something to yourself ?

Obviously I'm thinking this is total bullshit. I never thought about this and never will. But my mind keeps going like "Can we believe this statement? How can we actually prove that this is not a threat?" 

And no matter what I come up with, there is like nothing that could calm my anxiety and actually prove it to go "Oh okay got it. That's not a danger at all." 

Am I supposed to ignore this thought ? Not giving into the anxiety? Because it's really hard and I have a huge urge to prove my anxiety that this is not a real threat.. But you can't logically win against anxiety..
