Hi happysista!
After finding out my religion was nothing but a hoax, I started to take a critical look on everything I believed. I decided the best thing was to start from scratch. A good approach is the scientific method:
Don't believe anything unless there is proof to substanciate it or strong clues that cannot be explained otherwise. Use logic and rational thought. Look at things from multiple sides (pro and contra). Ask questions. Accordingly, make a decent evaluation and draw your own conclusions. Any belief system that rejects scrutiny and questioning should be rejected. Do not be impressed with authority, make your own choice and do not be too proud to admit you were wrong. Better learn from mistakes than stick to it!
I hope this helps! Good luck on your queste for truth.
