I can relate to this. My family is a bit fucked up and yes its really hard seeing this being passed down to nieces and nephews. My dad is currently trying to get off alcohol (after a 40+ year dependency, marriage breakdown, homelessness, several suicide attempts etc). He's doing really well actually, but has relapsed several times recently so I offered to facilitate him micro-dosing psilocybin (which I only just got into myself). He's a bit sceptical about it but he's a pretty open minded guy so he's giving it a go. We're only a week in so obviously no miraculous results but he does seem a bit chirpier. I'm not expecting miracles but I figure its worth a try as long as people are comfortable doing it.
I was unsure of whether this was the right thing to do as I am only a newbie myself but I guess time will tell if I'm an idiot or not
Ultimately everyone is responsible for themselves and I think working on ourselves is the best thing we can do for our family.
