I find this offensive and heartbreaking. Would you say anyone with a disability is a "mistake"? I wouldn't. Stuttering is a disability. As far as hardships, it definitely sucks, but, hey, it could always be worse. I hope you can find support that isn't Reddit - speech pathologist and counseling. If you look up on the internet there are stuttering therapy groups that are often free. Try to get yourself there. And if you need perspective on "mistakes", please volunteer at your local hospital or animal shelter. To live is to suffer. In the grand scheme, we have it alright. If you are religious, ask your minister (or the like) about Moses. He had a stutter and did incredible things!
