How does a wimpy grown man with no outdoor experience, who was pampered by a single mother as a child reliably learn about actual survival skills after passing adulthood?

I'm medically disqualified for military service and was never in any scouting groups as a child. Other than watching internet series and winging it, are there any alternatives that would offer an actual mentor to help learn these things? Or am I over-analyzing this and is being /out/ literally just figuring shit out yourself and hoping you don't get maimed by a boar in the process?

Help me understand this please /out/. I don't want to die as an office drone.
