Not quite the same circumstances (not at all, actually) but when we emigrated to OZ we brought a certain amount with us & left behind stuff too, as we just couldn't afford the shipment of all of it.
We now have a second hand bed for DD (new matress, of course) second hand desks 2, second hand TV cabinet & second hand bedside tables & second hand cofee tables. For a while dd had (and still has) second hand toys! We also borrowed a bed from family until ours came over. This is after owing an enitre 3 bed house full of stuff.
We do have some savings, but they are for a deposit on house in the future, I can live with second hand stuff, it's really NOT that hard.
I think she needs to be told no more money & needs to actually realise how careless she has been with the money granted to her. Other wise she will always expect others to bail her out.
