Hi and welcome Taylor
I'm sorry for your loss.
I've never been to rehab but I know others here have, and you're bound to hear from them soon.
as for question 3: I wanted a new life free of addiction and I've never stopped working for it.
I made choices and decisions based on wanting to stay clean and sober. I changed a lot of things in my life - people places things - cos my old life was all about drinking
A place like this (Sober Recovery) helped me a lot.
