Is it embarrassing to be 26 and still have a medium to severe stutter?

Is it embarrassing to be 26 and still have a medium to severe stutter? I’ve been stuttering ever since I was 4/5 years old and I’m 26 now. I’ve had phases (1-2 years) throughout my life when my stuttering reduced quite a bit and during those times, I used to think that I may be able to stop stuttering completely but then, it got more severe. As of right now, it’s moderate to severe and I can’t think of remedies as I feel like I’ve tried everything (deep-breathing exercises, speech therapy for 1.5 years when I was 19, thinking “positively” and being “optimistic” that my speech will improve) but right now, I feel as if I’m so old that trying anything doesn’t really matter.
