It's all good, dude.
I don't think there's a song you've done that I don't like, if that made any sense. This one is great. Silky smooth, good instrumentation, and the static in the background makes me think of the beach. Great song for driving, chilling, or summer in general. I've actually had it on repeat for the last 15 minutes or so, if that says anything. :)
I can kind of feel the emotion behind the song, and I can kind of sympathize with how you feel, what with the next part of your life about to start. The same thing happened to me last summer, and let me tell you, I had a hard time feeling anything but confused that entire summer. I couldn't really settle on any one emotion until I left home and got to college. Once I was there, though, everything got better. I can't do much other than speak for myself, and I don't know if this means anything to you, but you have a real talent for the music you make, and that's bound to get you to better places.
Here's hoping everything gets better for you. Keep doing what you're doing, never look back, and don't stop making awesome music. :)
