What you're experiencing is your unconscious mind's inability to accept the conclusion that your conscious self has reached. Repetitive, conscious reinforcement of the fact that the god you fear does not exist will help to get the parts of your brain beyond your control to accept that there is nothing to fear. You could do that by reading books about the arguments against god, participate in this forum, or even just keep reminding yourself on a daily basis that your consciousness surviving death only to be punished by a bearded man sitting on a cloud is just silliness.
It takes time, but if you work at it, you can speed up the process of alleviating the fear.

Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
