OK. I had to check. It really worries me that people have such free access to guns in some countries.

Very late here in Australia. Have to try for a few hrs sleep myself. I don't get much sleep some nights either. Sleep is a healing thing. I wish you a good night of sleep to help you through.

Hold on there. Think ahead. I know this might seem a silly thing to say, but when you get a break from your studies have you ever thought of doing some sort of community work. We have programmes here in Australia where people join together planting trees and cleaning out streams and things like that.

Sounds to me that you need a change of environment... but heck, what would I know.
