It seems that you got the answer already. Stop fighting your stuttering. Don´t try to speak more fluently. It does not work that way. Accept and let go. Trust in your body to do the work. When you apply more control to your speech it only make it worst. Rest. Sleep. It is considerable undervalue the power of sleeping and ensuring a good night rest. Better yet, a good week/month sleeping. Your nervous system will come to a better place. You will stutter less guarantee. There is a direct relation between stuttering and being tired and/or stress out. I would start there. By getting good quality sleep then try to work my stuttering step by step.
