I feel your frustration. I lost my voice on Friday, and could not speak at all. I taught a brand new sunday school class on Sunday morning, and could barely make sounds. We gave up after just a few minutes and everyone just visited. Today is the first day I have been able to speak on the phone to my clients. I am still raspy, but I can at least be understood. It has been seven days for me, and I'm still not normal. Hopefully your case will be different.
Thanks for providing the above link. It is a great site. I am reminded about how are feelings cannot be trusted. Thank God that our relationship with Him is not dependent on how I feel on a certain day. Real truth is not dependent on emotions.
