Pie, that sounds great, you're on the right path! Next I would suggest coming up with a list of GAL activities you want to try and make yourself do those things. It is very, very difficult at first. I know right now you'd rather curl up in a corner but you've got to get out and GAL to help yourself recuperate and get your mind off of things. Each time you go do something it gets easier and easier. Get in touch with old friends. Make new ones. Lift weights. Run. Play golf. Fly a kite, fly an R/C plane, build a model, volunteer at a food bank, join a poetry club, build houses with Habitat for Humanity. In short do anything... except make excuses!
Next make a list of 180's. This list is only for you, don't let anyone else see it. Refer to it as a reminder of what your goals are so you can keep working on them.
One critical thing Michele mentions in her books is the importance of actions. WAS simply do not believe anything you say. It all sounds like empty promises that they've heard a thousand times before. So don't SAY, DO. At first your 180's will seem to her like "tricks to get her back", so that's why it's important to stick with them. Over time she will come to believe your changes are real.
