Welcome to Atheist Nexus with its thousands of good friends.
A group you may like is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion..... ) with its 120 discussions and numerous video films.
How to feel good. One discussion (over 65 posts) is "Proud to be Atheist". There's much to be proud and feel good about because atheists and humanists hold the intellectual high ground that is so far removed from the pathetic superstitious god believers who are slaves to a controlling clergy and their imaginary beings.
