I don't think dumping it would do any good anyway...you don't really know how to stop, nor do I think you want to stop (you are emotionally invested in it). Logical arguments about saving money won't change
WHY you are doing it...it's a negative coping mechanism for all the pain you don't know how to deal with. It's very clear how much pain you are in when you drink too much and you post here, and I am sorry you are going through that.

I truly hope you find a new TT ASAP and that you can learn some new healthier coping mechanisms (you won't be able to stop drinking until you have something else to replace it with).
