Laryngitis?

I'm 14 and for the past couple of days i've had a pretty bad sore throat and chest congestion. Yesterday I began to lose my voice and ended up losing it completely, like absolutely nothing comes out when I try to talk. I stayed home from school today, but i'm scared because when I researched it it said it can last up to two weeks. I've been drinking tea and having soup but i'm a bit shaken up. I haven't been whispering so nothing gets more strained. But do you know anything I can do to get rid of it sooner? Will it really last for over a week?
