I think you are doing the best you can in this sticky situation. Keeping it light and not getting stressed is great. Is that a 180 for you? I know if you're anything like me that finances can get the stress up faster than most anything! I think you are handling it well.
One question about this trip to Stockholm. Why can't you just stay in a cheaper hotel room? Especially since the place tickets are non-refundable. You are already spending money you might as well get a little enjoyment out of it. Besides time away might help you clear your mind so you can start to be more productive at work.
