Karen,
Really sorry to hear about your incident, that is truely sad. I hope the people responsible were well punished!
In some ways, I'm kind of the opposite - I left home when I was just over 16, spent several years in collage / uni, but then travelled extensively with work (20 years!). Mainly Europe, Middle East, US and Africa. Although interested in Photography (I even ran a photography business for a while, photographing rally cars and selling the photo's to magazines and the sponsors), I never took my camera with me when travelling with work. As a consequence, I have great memories of loads of locations but no photo's to show for it
I still travel a fair bit and now take my camera with me; but rarely get a good opportunity to use it as now I'm in and out of locations generally overnight, and I usually like to travel as light as possible - just cabin luggage.
What I can say, from my experiences, is that although there is a lot of bad in the world - there is also an immense amount of good.
Glad you found the camera for two reasons - it's helped you & it's given us an opportunity to see your pictures
Phil
