Hello guys I'm 24 from Australia and I think i have a speech disorder. I've always felt like my speech is bad but now I actually think its a disorder. I don't officially have a speech disorder but i know i do. I also have anxiety disorder and i think the bad speech contributes to my anxiety because when I'm in a social situation I fear if i say something, it won't come out good and because it doesn't half the time.

My problem with my speech is I find it hard to say these words sometimes in a sentence.
- Sentences
- existence
- existence's
- and lots of words, especially words that have an s, 's at the end

Any ideas how i can improve my speech also no one actually knows i have a speech disorder.
