Welcome to Atheist Nexus with its 8000 good friends.
A useful group is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion....) with its 125 discussions and numerous video films.
One discussion (70 posts) is "Proud to be Atheist".
There's much to feel good about
because atheists and humanists hold the moral high ground—far removed from the world of the superstitious god believers with their imaginary heaven and hell.
