I need to take my own advice on this one too, but here it is:
There is NEVER a reason to be sad. Ever. Never ever ever ever. Moping around about stuff is stupid. Letting things get drawn out is stupid. Yes, i know it's virtually impossible to let some things NOT make you sad (i.e. breakups, divorce, death, etc.). But there should be a better way for us to deal with it than to bathe in the shitty emotions that are 'expected' with something like that.
I feel that if something shitty happens, get over it as fast as you can. Get your mind on the right path because no matter what the situation is for you, odds are you can't do anything about it, and your life will continue either way. Shit's gonna happen, and if you let it effect you for longer than it should, you're taking precious moments out of YOUR life for nothing!
You (and I) should work on accepting things the way that they happen and moving on as soon as you can. And there are entirely different ways to deal with every situation.
One of the hardest ones is death. People expect you to be morbidly upset for a while if someone you were close to dies. But why? that's the cliche. Death is natural, and it's going to happen. I'm not trying to all, 'whatever' about someone dying, but really. What does making yourself feel like shit about it for weeks, or months do to help anyone? Be happy that they lived a great life, and be happy that you had them in your life. You know that they weren't going to be around forever. Accept that there's nothing that can be done about it, and be happy for the time you had, because you'll never be able to enjoy those moments again if you concentrate on moments you never had with them.
And that's just one example, here.
So work on being able to move on as fast as you can because there's ALWAYS so much you can be happy about. ALWAYS.
My point in all this is very very simple. Never let people talk about you saying:
"that was a rough time in their life"
