I don't think I could ever become depressed. Like, my life isn't perfect or amazing or anything like that, but I just don't feel like I'd ever be able to actually be "depressed." I'm a happy person, and anyone can make me smile, so it'd just be really hard for me to be genuinely sad or lonely for more than a few minutes.
Edit: It may also be that I surround myself with happy people. I don't let people bring me down. If anything, hearing about people's problems sometimes annoys me.
