Welcome to Atheist Nexus with its 8300+ good friends. You will not be lonely here,
A useful group to join, with its 130 discussions and numerous video films, is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion....).
One discussion (72 posts) is "Proud to be Atheist". There's much to feel mentally good about because atheists and humanists hold the intellectual high ground——far from the mental slavery of superstitious people who submit to a narrow-minded controlling clergy with their imaginary god, heaven and hell.
