From my experience (25M), the more you think about it, the worse it'll get, you've to reach a stage where you just don't care anymore, and won't let that stop you from getting where you want to be in life. Just to be clear, this isn't something easy to achieve, you won't miracously stop stuttering, some people won't ever fully accept you, some will even laugh at your back, that unfortunately won't change, but the way you look at it can indeed change, that's up to you and is something you do have control over.
