Hi Dee
I don't use the label "atheist" to describe myself, although my views are atheistic, concerning supernatural deities (such as those in religions and mythologies). For a long time, I avoided labels, too, especially after discarding the label "Christian." However, increasingly, I am using "Humanist" to refer to my views and to myself. (For most of my life as a Christian, I was trying to emerge as a Humanist, and so for some years near the end, my views were a sort of Christian Humanism.) As you rightly discern and well state, "humanism is designed to provide a way of life, world view, etc." and I would add, a view of Humanity and of Self.
But you already know this about me.
Peace,
Being
