You're the one attacking people by calling them delusional just because they're able to find peace in what they have been dealt. Life is not perfect, you don't have to be, so it's not that people "pretend their disability isn't a big deal or a issue" they just acknowledge whatever situation that they are in and they try to make the best of it. I think it's delusional to look at someone that's going through something similar to you and if they don't feel the same way, they must be the problem and that doesn't mean you're the problem. Just two people that have different outlooks on life.
