Steroids worsen ADHD. You might "feel" better, but you definitely aren't performing better in your executive functions and emotional regulation. They also change dopamine system for the worst in the long run, which will make you even more ADHD. You wont really see this until you're a bit older and have more self regulation and self monitoring abilities. But by that time you'll be too fucked up to notice anything really, your world will be one big ball of confusion, much more so then it is now. Fellow ADHD'er here btw, ADHD-PI.
While you may be doing stupid irreversible damage to your periphery, your brain is going to suffer a lot too. Unfortunately, ADHD brains are much less robust then neurotypical brains and just simply can't take all the abuse you're throwing at them. It's one thing having a clear functional head with a broken body, but completely something else to having a broken mind. A heart attack that leads to instant death (not leaving half of your body or brain paralyzed - which is a very probable scenario) is imo nothing compared to being in a state of confused brain fog coupled with anxiety and total emotional dysregulation. You'll regret what you're doing, don't disregard all of our opinions, we are not just some dumb idiot's on the other side of the computer screen talking nonsense. If it was just a simple heart attack and puff you're gone, ok maybe, but all the other chit, no thank you, I'll pass.
