If we were already doing things right, why would we need therapy? My T's major message to me over the past few weeks has been not to sabotage myself. I'm not trying to mess things up for myself, but it's hard to do things differently. I hope to keep working on this as I transition to another therapist. I think therapy is worth it if you want to change and you're willing to try your best. Sometimes it takes a few (zillion) tries, but as long as I keep trying, then yay me.

[edit] Just read mroe of the thread and saw the bender "committment" thing. Who says you can't change your mind about that? If nothing else, at least be aware of what you're doing and why. For my own issues, just being aware of my habits and putting some distance between the urge and the action helped a lot. It made it less automatic and slowly helped me make changes. If drugs/alcohol are something you want to be different in your life, I would encourage you to explore what you're getting from it and how else you might get the feeling you're looking for (in a healthy way) or just a substitution that probably won't feel the same at all but could be an improvement to your quality of life. I hope you think about what you're wanting in your life and how you want to use therapy as a means to achieve that.
