Regardless of what I want, I will be here for a bit; I am overly cautious, so without foolproof circumstances I can't CTB. I will hang myself someday, whether it be in three months, three years, or three decades.
If I had everything I wanted, I'd still CTB. From a very young age, I've accepted that I would die by suicide. For one, it puts the ultimate control in my hands, and it keeps my dignity in tact—providing I don't die of a health complication first, I can prevent degeneration of my body before I'm elderly and dependent. And sicker. And most importantly uglier.
My best case scenario is living until about 45-50, and my tolerable scenario if I can get a hold of my life will be to die around 30-35. So long as I can function, hold a job, attain a few cosmetic procedures and manage my health, I'm good until then. (Unlikely, tbh) Most likely, I'll still be a NEET by 23 and if I'm not enrolled in anything then I will attempt to get around my living situation to off myself.
