Suicidal Redditors are usually up to their eyeballs in debt or have other severe issues, so this comes off a bit silly. Anyway, we should be careful when it comes to some of these cases. They've got a point. Some autist looksmax users with no real issues tend to see their lives as not worth living because they are not a multi-millionaire with a harem. These people are not Incels, just young losers with delusional expectations from life.
Autism, in his case, is probably self-diagnosed, and small probably means 5.5 NBP. Even the height is not so bad. I'm 5'9'', and while it is a bad height, it is not death tier.
