I would answer: Normally. Just like every other goddamn atheist. Knowing that there is no God is scary at first but then you realize YOU are in charge of your own morals. YOU decide whether homosexuality is good or bad and don't need anyone to tell you. Once you realize that, you can become more moral than you ever have been because there is no one telling you that your intrinsic morality is wrong.

Furthermore, not believing in the afterlife means you take greater care to live this life as best as you can. Automatically, this leads to a better life for you and everyone else around you. Once you get over the 'death and then nothing' fact life gets so much better...

Basically, after you stop believing in God, life becomes about living IN the moment, rather than for the moment which might come after you die. One can finally enjoy everything without fearing that he might be judged for it.

The first step to atheism is only difficult because it's difficult to believe in the above. However, I don't know any atheist or religious person turned atheist who would say that their atheism makes their lives worse. One should take note when every atheist praises atheism, while every 'Christian' is afraid to think for themselves because they might be judged for it after they die.
