Assuming you've been around for a while, you've probably seen me joke about my bad finances, my broken bones, crippling depression and chronic pain (just to name a few). None of these situations are particularly desirable and I can tell you first hand... that shit hurts. Regardless, I tend to take it with a bit of humor. Life would be quite depressing if I didn't, and wallowing in self-pity never improved anything.
I expect anyone in their right mind to know that broken bones, depression and illness are awful and cause suffering, as do many other things that we casually joke about in life. These are hard topics to talk about. From my experience, topics that people often avoid because they're afraid. Making a joke or two about it actually opens it up for discussion, taking away the heaviness of the subject matter, and having people ask honest questions without the fear of hurting my feelings. My pain shaped me, but it doesn't define me as a whole. I have many positive qualities that I'd rather answer for, instead of those few aspects in life that didn't quite work out for me.
If you're suffering, keep in mind that it's situational. It's something you go through, not something you are. Get some help to sort out your issues (medical, or otherwise) but also learn to laugh at the absurdities that life throws at you. You might not be able to change a situation, but the way you choose to look at it makes a world of difference.
