This is a hard post to write. It might be a hard post to read. It might offend, it might confuse. And honestly, if it does either, I'm not really sorry at all.
I've had a couple brave friends confess to me lately that sometimes when I talk about my health (either in person or online), sometimes they don't know what to say. That they feel bad for what I'm going through and want to support me, but don't know how to do that, or what I need.
It's hard to talk to people who are chronically ill if you haven't experienced it yourself. (I won't speak for anyone with a terminal illness, as I very thankfully haven't had to go down that road myself). But it's not impossible. All you need is an open mind, and the willingness to throw away your assumptions or beliefs about what they are experiencing.
Before trying to explain what to say, I want to go through some basics on what not to say.
