I know you are under a lot of stress, but if you can manage to stick with the plan, it will take much less time than going back to renting. Imagine that rent check every month going into your house investment! Once school starts, maybe you could find a part time job or volunteer somewhere for a few hours a week. Libraries are a nice quiet place to volunteer. Anything to get out of the house for a few hours a week.
I've been thinking about that a lot. Wonder if I'm ready to head back to work.
