I'm 25 and have stuttered for as long as I can remember. Although its on the milder side its still noticeable and has hindered my social life. I've learned to deal with dark thoughts by realizing that there's no benefit in letting something I cant change and have no control over hold me back in life. I also realized that yes I have a stutter but it could be much worse there are people out there dealing with worse issues like cancer, incurable diseases, homelessness, etc and I have so much to be thankful for. Everyone has flaws it just happens that ours is in our speech and isn't as easy to hide.
