Lexie, it's great that the bedroom is nearly done!! That is really excellent progress - don't get down on yourself - celebrate!! Isn't this one of those one-day-at-a-time (one room, one bookcase, one box or bag of stuff...) things?
Is there any chance that this lady can work with you remotely in some way? Skype, email, etc.? I'm just trying to think of things at might help you maintain this momentum.
You are so smart and capable. You absolutely CAN do this.
