Hi Lunarain, thanks for sharing with us. Don't worry, at 2.5 weeks post op after Yeson I could still barely make a noise due to inflammation of the vocal folds (laryngitis).
Try to keep your head on straight and know that you will get it back!
Oh and I can't believe he did not tell you not to whisper- it is actually really bad for healing vocal chords. Turbulent air over the folds increases dryness, puts undue tension on them, and will likely delay your healing. At least, that is what Dr. Kim at Yeson told me. For me it was absolutely no whispering until 2 months. And even after that, not recommended (for any voice, VFS or not).
Anyway I am sure your voice will turn out. It only takes a little bit of swelling to make a person lose their voice. You are probably just a person who tends to swell more than average- which is fine! Just be easy (no whispering, especially loud whispering) and the edema should clear up. Trust your doctor 🙂
