Sorry to hear about the deaths and injuries. Inna lillahi wo inna ilaihi rajiun.

Hopefully the foreign nations are ones you never heard about because they're small and uneventful and not because they're chaotic and crazy and not someplace you would want to be. Sounds like you're in med school so I'm not sure if fun would necessarily be the right word? But then again, I don't really know you so I'm gonna go ahead and say it anyway: Hope you're having fun in these foreign lands!

I think that our views of the world are always changing, even if by so negligible an amount over the course of seconds, minutes, and days, that they are imperceptible to us until enough time has gone by. So, inshAllah, whatever it is you've been through, are going through, and will go through, the acquisition of wisdom leads to happiness for you. That's my wish for you :)
