Usually around 5, sometimes a bit lower, sometimes a bit higher. Often I'll be a 8 for a while, or a 2. Sometimes I suddenly feel suicidal, like 9 or 10
Right now? 0, my brain happens to be having a good day, and I have a personal project to look forward to.
But constantly: There's no place for me, nothing to look forwards too. All these annoying things and responsibilities just to be able to pass the time until I die? No hope, no success, I'm basically a failure. Why do I even live? Why don't I end it already? The only difference with "zero" and "ten" is really just how I care about those things right now, and if the thing to pass this life over is enjoyable enough, like that game or my project.
