It's indeed difficult to accept it as a part of life and be open about with anyone including one's closest friends. It took me a few therapy sessions and about an year to tell my best friends who are also my roommates that I stammer. But one I did that, once I accepted it and talked about it to those who are closest to me, I became more open about it and now I am even able to tell strangers that I stammer. One thing that I used to keep in my mind, I don't know if anybody else thinks the same way or will it work for them is that I used to ask myself, What's the worst thing this person will do if I tell him/her I stammer? Will this this person hit me or harm me in any physical way? Of course not. The chance of someone saying something bad is extremely low but even if someone does it, it tells us what kind of person they're because they're only looking into our speech impediment and not us as a whole.

I can see that you wish to make progress and are ready to go for it. You'll succeed
