"I’m not depressed, at least I don’t think I am. I don’t really feel sad."

Definitely sounds familiar to my experience a couple years before my depression diagnosis. I'm not saying that I think you're depressed, it definitely manifests differently from person to person. For me it feels like a really heavy blanket draped over my mind that holds me down from doing the things I want to, but I am very comfortable underneath that blanket.

Im going to check out your song when I have time later today. I hope you continue making music, we all need something to put ourselves into.

Edit: I just listened to the song, super heart felt and full of emotion. You've gotta make time to do more of that.
