I never wanted to be an actor - I deal with dysarthia, stuttering and blocking - but I did want to be in performance. So I got into drama school and got my degree, I recently got a job acting and I was told that my voice, the dragged, stuttered, f'cked up thing, was actually good because it had 'character'. Early am-dram, my voice had been framed as incredibly problematic- but after a certain level of training, it isn't anymore because it becomes seen as a decision (even though it really isn't) and in the world of performance I am in, seen as an thing of authenticity rather than pretense. I will undoubtedly get some people being bad about it again, but now I have the training behind me to feel assured in telling them to get lost. I guess my advice would be get back into it, because it's really not beyond your capacity, maybe it was jsut beyond the capacity of the people you were being trained by.
