Hello Dear, I am so sorry to hear that you are feeling this way. Coming out to family and friends as an atheist can be a really big deal. Its always a bigger issues with parents because they have an image in their minds of the sort of life they want you to live and they me not be the kind of life that you will choose for yourself.

You don't have to believe in anything that does not ring true. I am also an Atheist and I am here if you ever need to to talk.
