A Horribly Un-Funny Laughing Matter

I'm going to start by explaining why my problem is a problem, by telling you about a time earlier in my still ongoing childhood. Back when I was training in marshal arts. I was at the young age where you tend to get tickled, and that meant nothing good for me. See, in my family, laughter is rare, and the only laugh we can laugh when we laugh is spontaneous and painful. The spontaneous laughter has a similar effect to grabbing a cat by the scruff of the neck. But in that scenario, the cat has a lot more control, and isn't in pain. So it is more like a taser. When I laugh, I can't stop, and I slump over, trying to keep breathing, unable to get up or move around much, my lungs, ribs, heart, and stomach being painfully battered. Same goes with my mom. Now, luckily for us, we don't laugh at much very often. But tickling, as you can imagine, is the bane of my family, because it forces us to laugh. And back at that training facility, my instructor, nor my mother, knew that I hated being tickled. Why? It is very hard to speak or retaliate in any way while your lungs are destroying themselves. Thankfully, I finally managed to solve that specific problem. But the problem, if not specifically tickling, is back. Because of a funny video I made of my cat. I originally recorded the video to reward my class for doing their work, but before I went to school the next day, I showed the video to my mom, to ask what she thought. Unexpectedly, she started laughing. And in my family, when one person starts laughing, so does everybody else. And that is what happened. Instantly, we were again exposed to our bane. And since then, my mother has played the video a few more times, each time putting the entire family out of order for a good amount of time. And one thing that makes this particularly bad is the fact that my mom has had stomach surgery relatively recently, and this is doing nothing good for her.
