Nothing wrong with being an atheist or an introvert, those are totally legitimate beliefs and personality types.

Faith totally worked for me, and might work for you or anyone else too. I didn't include my specific beliefs and community because it may not be for everyone, but if you can get similar benefits (community, hope, belonging, volunteering) from any other positive place then more power to you!

Life is an interesting journey, and I hope you can live it to its fullest :)
