Lilly, you will build a life even better. Please try to keep the focus on YOU and on the things that bring you happiness, and try to get past this sick chapter as quickly as time permits you to do so. Reconstructing a life can be difficult but can also be a time of great joy....at least it was for me.
There are many addicts who mix drugs and alcohol...it's quite common. My X did it. But does it really matter? He was not someone I wanted in my life any more, and I ceased to care what he was putting in his body. It was no longer my problem. Does that make sense?
