Lost my voice for a while now ! Help !?

So i got food poisoning on Monday, and that cleared out of my system. But on Tuesday I COMPLETELY lost my voice, & Its still not back. I missed pretty much this whole week of work, but I cant mis Monday. And my job involves talking, so I need my voice to be back by then. I've tried everything, ( Inhaling steam, gargling salt water, drinking tea) I Dont know what else to do! Please help :)
