Here's a different angle you might consider: There's no guarantee that if you hadn't stuttered, your life would have been ideal. Imagining what could have been is a problematic exercise, since it doesn't deal with a real world. It only portrays an imagined change and wishful thinking for all the rest. To put it differently: If something could have been different, everything could have been different. You might never have met your girlfriend, for example. This kind of exercise is thusly quite unfruitful. The better way to deal with the notion of "a better world" is to focus on the good things you have - instead of the good things you imagine you could have had (which is of course a fundamentally broken notion). Life is what it is. It's up to us to make the best of it. There's no alternative we missed, or that was promised us. This life is ours - make sure to perceive it fully, and not just regret the bad stuff. Regret is just the ghost of past pain haunting you! Shoo it away, I say. Hug your girlfriend. :)
