Do I have water damage?

I had a glass of water behind my bed, and my ipod was near it in the back of the bed. I went into my room after school to get my ipod to charge it, and It was wet and seemed like there was water inside the screen as well. It seemed the ipod had fallen into the water, but I wasn't sure. It powered on, but as I was holding it in my hand about 3 minutes later it completely shut off. I went to charge it but charging it would not make the screen turn on. I forgot how to factory reset the ipod, so maybe it just shut off? I don't know how to fix water damage, but I've had this ipod for about 6 years now.

I really need to know what to do. It will not turn on.

Please help. I don't know how to take apart the ipod and have never dealt with something like this before.
