Tips for words starting with the 'u-' or 'you-' sound? (AGAIN)

Tips for words starting with the 'u-' or 'you-' sound? (AGAIN) Hey guys! I had previously made a post stating how I stammer EXCLUSIVELY(mostly) at words with starting with the 'u-' or 'you-' sound.I'd gotten an extremely helpful tip, which was prefixing those words with the 'e-' sound. It actually worked, I was beyond ecstatic. Then, for about 1.5 months, I had no issues at all! Everything was wonderful! But from the last week, I've(for some reason) not been able to utilize this technique anymore? The 'e-' sound just doesn't come out of my mouth(right before I can attempt to say the 'you-' sound). This is bringing back unwelcome memories and further adding to my anxiety, which in turn increase my chances of stuttering. ​ Can anyone please give some insights onto this?? Or any new hack which worked for you? Thank you
