Voice damaged and difficult to speak.

10-12 days back I suddenly felt sore throat. I thought due to climate change or throat infection. I consult a doc, he gave cefixime for 5 days. But i didn't get relief. Again consulted another he told for laryngitis then i was given 3 days amoxcillin. Didnt recovered much and then i consulted MS ENT he told me same problem and given steriod (dexo) amd amoxycline for 5 days. Today is 5th day of EnT medicine. Upto yesterday i felt 50% Ok.. Bit today morning when i wakeup condition was very bad. I was not able to speak a single word even. I tried for 2 hrs then i took steam after which i am able to speak little. I am again worried that what to do? I am basically teacher. So my voice is my everything. Please suggest me best to heal this problem.. Feeling low after somuch anitbiotics and low result
