Growing up, I hated God too for my stutter. Until I became an atheist. 20 years later, I still stutter and still have a lot of difficulty at work because of it, but a lot has changed in the way I think. I started to believe in God again and I like to look at this as a test or an absolvent for my sins. Either way (if you believe in God or not) that’s ok as long as you keep you chin up and never stand down or let your stuttering hold you back.
