987g.......I don't really know the origin of this problem for you, of course.
I would caution, though, not to blame everything on alcoholism or co-dependency. It could be something about the job, itself!!
There are tons of people who are in jobs that they are not suited for---one reason or another.
I do know that if you are in the wrong job--it can be a bleeping misery!!!!
I can remember going through a tough personal time....and, my job was actually a relief for me.....HOWEVER, I loved my job, at that time.
If you are in the wrong job...I say to change the job (or career) as soon as humanly possible.....
