Hey there, every stutter goes through this phase. Even I can remember like 3 years again I was so depressed that i had a feeling- Whenever I open my mouth I feel more frustration that de**h literally. But i tried to find some self help geoup, that helped me a lot. Like here in India there is are group of stammers who can connect and talk and practice. Try to find a group and try to connect, it's a phase of frustration and it will go away. Just find like minded people. Hope your healing faster...
