Don't worry. It's much more easy to say than to do. Everything happens for a reason and most of the time we can't control it. We can't control it because we can not control what other people do, say, or think. Sadly all we can do is just control how we deal with it. The best thing we can do is to not worry. Worrying causes so many mental and even physical issues. I know getting bad news or going through tough situations are hard. Talk it out with a friend, give it some time, and just remember that everything happens for a reason. You'll end up happy, and if you're not then you know it's not the end yet.
