I see some parallels but my own problems spiralled a bit further than yours. I was struggling with hallucinations and paranoia on and off for a period of a few years in my early twenties (but luckily didn't leave a trace on social media).

It started after a period of habitual smoking and got progressively worse anytime I smoked. Mental health ward twice (once in a country where I didn't speak the language, but that's another story). Haven't had any problems since I cleaned up my lifestyle and fully ditched weed many years ago. These days I'm also happily married with kids (three), a house and a decent career.
