I too, have a severe stutter. For context, went to an intensive speech clinic back in the 90s and they said I was one of the most severe cases they have ever seen. I had your sentiment for a long time. It was far from easy to accept my stutter. At 39 I can say I am now fully accepting of it, but it was a journey that took me over a decade to figure it all out. Decades of behavior and thought process take a long time to reverse. I feel so free now and stuttering is no longer my anchor in life. If you feel acceptance is unattainable for you right now, perhaps try to gain control of your stutter instead of the stutter controlling you. There is a lot to this, but it's a lot of desensitization, avoidance reduction, pushing yourself outside your comfort zone etc. You will actually find fluency to be a by-product of this. It's not easy. You will find your path. If you ever need to talk, feel free to drop me a line.
