Hi and welcome to the place that will help you breathe !!!
There's alot of smart people in here that can lend an ear and give some really good advice (you don't need to take any just for the record, lol)
I am the mother of a recovering heroin addict. he is 25 now I was going to tell you how long he's been clean but it doesn't really matter. You see the chance of relapse is always there and learning to let go and know it's his life and choice is a process for sure. I am pretty good about his addiction now but there are times!!!! Unfortunately.
Try to keep in mind that you have your own life and you need to live it the best way you can. Read all the post you can on this site and something will hit you that will help you on your way to keeping your sanity.
i don't know what I would have done if I didn't stumble upon this site, it has helped me so much that I wouldn't know where to begin.
Good Luck in your quest for some peace, you'll find it, your not alone.
