Understandable.
Some reality hammer here, being adult does not mean those problems magically goes away. Especially on today community, where doing good out of good will can makes you labelled in negative way, and everyone watch it will believe what they watched, not caring in what is actually happening.
But being adult gives you option to ignore those shits, to go your own way before it overwhelms you.
Just don't get too addicted to smoke or booze, just a little is fine.
