I think rather than thinking that all these things are different addictions, maybe its best to think of them as one addiction manifesting themselves in different ways.
Nows its time to let your addiction go - regardless of what form its tormenting you with this week.
You mentioned help - I think think that a great idea, whether its posting here, AA and the Steps, speaking with your doctor and therapist, inpatient or outpatient rehab - whatever you can do, now's the time to do it. Don't wait another day.
I think you'll have to accept a certain amount of discomfort for a while David, but its worth it.
