I've said this before, here, and in other places. No one...NO one...cares that you (we) have MS. They don't want to confront having a chronic illness, they don't want to deal with a possible negative outcome (death..although death isn't common with MS, it is with other chronic illnesses, and they don't make a distinction between MS and something terminal). People without a chronic illness, without a long-term disability, don't understand..and generally don't want to understand...what we have to deal with every day, just to get out of bed, sometimes.
Leaving literature around may make YOU feel better...but it likely will do little to educate anyone. If there WAS someone in your office who REALLY wanted to know about you, they would have asked by now, in a discrete and distinct way, so that you'd know that they really care.
When people ask you, "Hi, how are you?" they don't REALLY want to know about every thing that might be wrong with you that day. All they are doing is starting a conversation. Your reply should always be, "Fine, thanks, and you?" and move on to something else. If you instead respond with a litany of what is ailing you, they'll first get bored, then get put off, and indeed will start thinking of you as a hypochondriac, or crazy, or a whiner, or complainer. So the only good response is, "Fine, thanks, and you??" and let it go.
Indeed, if you really are uncomfortable with that, then a counselor would be a good listening ear. They're used to talking about and hearing about chronic illness, and won't be put off. And maybe you'll feel better. And yes, in time, you'll find a way to balance your health issues with "living a normal life like you used to", and it won't be a center focus of your conversations. Then you can come out of your office and interact "normally" with the "normal" folks who work there. And you'll all feel more comfortable.
