Mystik, maybe there are other areas you could work on during the extra hours off even if you weren't in therapy. Those hours could be so good for you. You've told us that things have been sliding in many areas because of your depression.
What if you took the extra time off and used it to fill up your cup? Like re-doing a room at home the way you and your son would enjoy it. Or, spending an afternoon sipping coffee at the bookstore enjoying a new book or magazine. Or, joining a mom's group in your area. Or, a bible study. I could go on but you get the point.
This could be a really good way to boost your therapy time. Instead of trying to be everywhere all the time, maybe this is the time to give yourself a break. At least for a few weeks.
