Could you email your doctor? If not do you have a friend who could speak to the doctor on the video for you? You can hear so could write the answers on a pad for your friend to relay to the doctor.
If you can't communicate with the doctor or get to the surgery then go to A&E.
Tambo, I'm sure it's not the end.
I had this once and GP diagnosed laryngitis .
After having it for 3/4 weeks, he referred me to ENT and I was told I had vocal chord paralysis.
It did clear up on it's own eventually, but you should have been referred by your GP if you've had it this long.
