Good question, good that you asked it. Suicidal people are not always depressed. This example is me, until the age of 17 I had severe depression, suicidal thoughts often visited me, but at the same time I was happier getting positive emotions from video games, movies and series. Now I am 23, my emotional state has stabilized and I do not want to impulsively kill myself, on the other hand, life has become less enjoyable. I still want to die because my health is getting worse every year, my appearance is just as ugly and I just don't see the point in living if I don't want to make a family and go to work just to have something to eat. Rather, I regret that I didn't kill myself at the age of 15-16, then I was more confident and after a while I can say that nothing worthwhile happened in my life for which it would be worth living if they told me what awaits me in the future. But on the other hand, I now have no fear of death and I do not believe in reincarnation, hell, heaven and other nonsense. Now I have a good way (opiates) and a bad life) I have situations in my head that trigger my psyche and make me remember all the shit that happened to me, probably when I doubt the last sip of drugs, I will say to myself: "dude , you have experienced so much shit, is there any point in suffer and living on?"
