I are Triste because potential depression issues which, when I'm not just feeling completely emotionally numb and physically drained generally leave me feeling sad and lonely. Although, tbh, I don't feel right stating with certainty that it is depression, since I have never gotten anything diagnosed.
And also, my username is the name of one of my first OCs, which I really need to actually write with more, and it loosely translates to "sad fate", which sounds like it would make for a cliche plotline, but I used to actually have some really cool ideas that I never bothered to right down for it.
