Oh wow, this is difficult, and I see (and think I really understand) your frustration, but reading your post, I have to admit I was beginning to wonder if Freedom wasn't right with what she said; that you're asking too much of you because you grew up overprotected (which is absolutely understandable from your parents' point of view), and because all you ever wanted is to live a "normal" life. And maybe your friends have become so protective now because they see you overdoing things...

I think the key (for everyone with a chonical illness) is acceptance. To accept that there are certain things you cannot (or at least shouldn't) do, but that apart from these things, your life is as normal as possible, and this is something the people around you should respect as well. Maybe they will stop caring too much about your medical condition if you are taking more care of yourself?
