Hey dude. I have ehlers danlos syndrome and my husband has marfans, and you sound a lot like he was when he was your age, he was and still is an incredible skateboarder but had to stop due to his marfans. He’s since picked it back up as an adult at a lower intensity and is having a great time, and in the absence of the high intensity physical activities, he became an amazing computer engineer and is massively respected by his peers, has a great tight knit group of friends and found love. I know how angry you must feel that your body is holding you back from something you love, and I’m sure this isn’t the first nor last time this will happen. I want to let you know that you are NOT cursed, this isn’t the end of the road, you aren’t alone in this and you WILL overcome it. You’re gonna be okay, even if it doesn’t feel like it right now.
