Have you even gone to a speech group? Like a therapy thing? There are always people worse than you. It's all about not caring. Sounds stupid. Sometimes I catch myself trying to hide the stutter. This just makes me angry. Best thing to do is allow yourself to stutter. My classic line is 'wow I really can't speak today'. It's a brush off but it's better than substituting words, sounding silly and ridiculous pauses. Just let it flow and you'll feel better. I really hope that helps. My stammer is so internal, my best friends didn't know until last year. I'm 26. I'm a pro, but that's not healthy.
