Am I Damaging My Hearing?

I listen to music a lot. Sometimes hours in a day. I use earphones, and I usually turn the volume pretty high. My parents always told me I would go deaf, but I ignored them. For the past month, whenever a decently loud sound goes off, my right ear rings for a couple of seconds. It's just my right ear. It doesn't even need to be that loud of a sound, just louder than normal. It happens almost every day, multiple times a day. Today, I realized that often when I smile, my right ear feels like it has water in it. It's kind of hard to explain, but that's what it feels like. Again, it's just my right ear. I'm a teenager, if that helps. Is my hearing my hearing being damaged? If so, what can I do? Thanks.
