Quality Not Quantity
If "echad hamarbeh ve'echad ha'ma'amit..." [whether you collect more or less, the end result is the same - reference to manna - edit.] ever applied to anything, it applies to recovery: It is quality, not quantity that matters above all. So if, for example, the weekly phone meetings are a big deal for you, and you attend them faithfully and try your best to use (work) whatever tools are placed at your disposal, you will get better! There are plenty folks who go to live meetings in person even five times a week - and still do not get better! So, surely, the attitude, honesty, and desperation are what really matters. The rest is really siyata di'Shmaya [G-d's Help]!
