You might not have verbal communication skills right now but you do have communication skills.

First lets look at what skills you have available that you can use right now. You are able to communicate here on the forum so you could write a message to someone to get help.

I was 24/7 caregiver for my parents. My mom was on oxygen full time and could only whisper. I bought her a bear whistle to wear around her neck so she could blow it to get my attention. I also put a bicycle horn on her walker so she could make noise with that. I also bought a canned air horn so she could make a very loud noise if I was outside.

You just need to think out of the box about what is available and how you can use it. Another resource might be to learn how to use the phone system that hearing impaired people use.

Good Luck and I hope you gain your voice back sooner rather than later.
