Quote:"Does God exist?"
But this is not what you really mean, is it? Mankind has invented thousands of gods and I assume you have never given 99.99% of them a passing thought.
What you really mean is "does MY god exist?" The fact is there is no more evidence for your god (or former god, if you like) than any of the others.
If the deist god exists....a 'god' who set everything up and then flew away somewhere to spend the rest of eternity jerking off....so what? 'God' becomes irrelevant at that point.
You get one life. Live it for yourself. And keep seeing those mental health professionals because as has been noted, we are not professionals and OCD can fuck you up.
