Noon...so sorry. Hugs. Try to breathe. None of us can really know the future (people keep reminding me) I share some of the situations you do, but not the heroin.
The drugs aren't helping, they ARE hurting, so even though you have challenges ahead, you are still going to make your life better if you get clean and stay clean.
There is no magic fix for any of this. We have to want it and finding that hope can be hard. Please stick around SR and read a LOT. When I am low on hope, I am often able to scrounge some up by hearing the stories of other people.
