i cant speak for myself on whats good and whats right. This worked for me so in my books - this is right...
I was really using weed as an escape from work and my family's problems. my wake up call is suddenly realizing im sacrificing my rent money, food money and my friendships just to buy weed.
what i did to quit that is to quit everything. I resigned, I cut off my family, I talked to friends told them I'm losing myself and that I want to kill myself.
which i did i killed myself in all ways except physical. I went to a completely new place and just let go of whats important.
honestly i cannot function without hyperfixation, so i obsessed on creating a new me and that kept me away from drugs
idk why you do weed but i dont think its super bad if done moderately. and i also dont think its impossible to stop if you want
tldr: i got a new addiction that is self-destructive but not in a way that will physically kill me

Ngl the consistency of this manhua updating over the years is amazing, over the course of this story I had 3 ex-bf and got addicted to weed then rehab then I'm finally free. I guess some things in this world is just constant like this godforsaken story
