Sickness

I understand sickness comes from the sin that adam and eve started. But I don't like that it was pass down to us, as children to get down syndrome or whatever else we could get, I know its a result of sin but I still don't like that it was the "punishment" for us. I hate the feeling whenever I see a someone like that, its not their fault, and I don't want sympathizing them, I don't want thinking they are not us, it makes me feel like I'm putting him/her to a different lower group. But I can't take how it is being like it is. However I know they need like others maybe even more, and maybe that's why I don't know how to accept it, and maybe I'm scared to love more:/ that's it Idk how to, well it took me awhile to think this through but at least I did.
