Most speech "therapy" is shit. And yes it's still politically correct to make fun of stuttering and dismiss it. Ive felt the same way like id rather not talk and just be mute or just end my life. Im reading a book from Lee Lovett called "How to Stop Stuttering and Love Speaking" and he hit the nail on the head. Stuttering is like a snowball, it either constantly getting worse or constantly getting better. I think you can slowly dig yourself out of this but the improvement will be slow and gradual. Please check the book out, i was 22 13 years ago and its normal to feel like a piece of sh!t loser if you're a dude (check out Coach Greg Adams and the Free Agent Lifestyle Channel). You can only improve from here, you can do it! i dont know you but i believe in you
