I can't function.

I can't function. Ever since an extremely stressful/traumatic event a month ago, my stutter has gone from moderate to severe. I find it very difficult to complete simple sentences without getting completely stuck. I always found ways around my stutter before, and didn't have trouble with my social or professional life, but now it's clear to me that this will destroy me. I can't even talk to my own family anymore without being totally incomprehensible. I've tried to eradicate the root of my stress, but keep failing. What can I do?
