I don't believe in god - in my day to day reality, there is no god to guide me. I don't have a concise notion of right and wrong - though I'm not sure that this would change if I did believe in god.
Nonetheless, I feel bad when I hurt people. I don't think we are free to do whatever we want, but those limitations aren't imposed by a god, or even by any mystical force of morality. There are consequences to actions, cause and effect, without there being a god.
None of this shows evidence whether god is real or not. You're just arguing that we need the illusion of god in order to seek out goodness (even though that fails among believers all the time). You may think that sounds nice, but if god isn't real, yet morality is dependent upon god, then morality isn't real also. And so what are you worried about? If you are an atheist who thinks morality is dependent upon god belief, you yourself must be amoral, and you could surely not have any basis to complain when people do things perceived to be "immoral". There would be no such thing to you. All things would be equal and the wrongdoings of the world would not phase you.
By the same token, if you're an atheist who thinks that meaning & purpose in life is dependent upon god (again, not true), and that a meaningless existence is a bad thing (is it?), then you must be a terribly conflicted person. Life must be meaningless to you and you must surely find a problem with that. Are you really a strong-willed person if you think people need such an illusion in order to hide from reality rather than dealing with it?
So there's a great deal of inconsistency in your argument, apart from a lot of bullshit also.
