I'm happy for you - it seems you are really ready this time. A whole new world awaits you, & you never have to return to hell.
I'd be careful about blaming yourself for other's addictions, though. You may have coaxed some people, but in the end it was their decision. Guilt is a destructive emotion. Once you acknowledge what you did & vow to never be that person again - don't keep blaming yourself. Trust me, I went down that road & it held me back from recovering.
Glad you are here with us sharing your determination. Please let us know how it's going.
