It's just a sad turn of events but what can someone do whenever his family is in need and no one was there to help?
That's just how life goes and thank god you were able to keep that bitcoins of yours until you really need them and it's not really bad to spend it that way because family should come first and when you want to invest again with your spares money, you always welcome and just be careful next time because it's really not recommendable to keep your BTC in some exchanges while you holding it. better consider having a personal Bitcoin wallet if you could do so.
