Trust me there is plenty of light.I am in the same boat.My husband has had a life long battle with drugs.Got clean finally.We were hit by Katrina and all looked hopeless.But things turned around and were good for a while.Had some ups and downs and he started drinking for a short time.I confronted him when I had proof of this and I hope it was just a short fall from the wagon but he is in that depression again.I feel like I am his mother not his wife and sometimes I am consumed by his problems.I am concerned he is bi polar(mildly).But I have to stay focused on me and can't get too caught up in it.Sometimes we have to put ourselves first.
