I don't know if this is true for you, but for me, recognizing that what I'm doing is a BAD habit...is a big thing. Before this past year, I thought what I was doing was the way I was supposed to do it.
In times of stress, everyone is bound to slip back into a pattern that they are comfortable with. It helps us deal with the stress.
The fact that you recognize what you are doing and also recognize that it's not constructive is wonderful!
