Do you think depression is predetermined in your DNA?

I've always been depressed. I'm looking at my baby pictures and I never looked happy or found joy in anything. Even at 3 years old I looked unhappy in literally every picture. I don't tell people I'm depressed or anything. I dont even like that word and I hate to use it but it's true.
It's a boredom like I just want to leave the planet and stop living. Do you think depression is predetermined?
