Missed out on majority of my youth, honestly no point anymore

I turn 25 this November. I technically have my "youth" for another 2 months. The accepted definition of "youth", generally ages 15-24, passed me by and I have ONE accomplishment to show for it.

Not just the formative experiences, but the little mundane things too, are forever in the past. You know what I have to look forward to now? Literally nothing.

I don't wanna hear "you're still young you've got plenty of time" because it's fucking bullshit. Your childhood/youth is for you to explore, have fun, live vicariously and plan for the future. I wasted all that. I never tried. I didn't end up with a fancy degree or accolades from school, just a degree in Advanced McDonalds management. I have no friends remaining from my childhood. They all moved on with their lives.

I see 3 paths before me: 1) Thug it out, keep living for another 40-50 years, and die alone in a nursing home. 2) Try thugging it out, put in effort but get shot down like a pig in the street for nothing b/c thats how fairness works in this world. 3) Just blow my head off now.

I understand that this is all self-inflicted; I'm the one who made bad choices. But why should I be forced to keep living a meaningless existance?
