Is atheism a liberating and good experience?

[Gilgamesh]

I can't sleep at night, I don't eat properly, I don't exercise enough any more, I have panic attacks, pains in my neck, migraines, flashing vision etc. and I have little self-esteem or genuine feeling of empathy or compassion for others.

And what does this have to do with atheism? Nothing.

Maybe you were more happy before atheism because you belonged to a social circle with the main focus being on religious beliefs? Humans are social creatures and when one isn't socialising, one can become depressed.

Having found the "one true universal truth" may be a delusion ya know. After all, somebody has to be wrong - right?

This, too, has nothing to do with atheism.
