some people just don't stop to think outside themselves.....till it happens to them.And that was RUDE of them!

Gaslighting! I would say something snappy, like "Oh, you seem to know a lot about hypochondria! When were you diagnosed?", then I'd walk away. Unless it was my boss, that is! 😆
What matters is what you know. If someone made hurtful comments like that, we would never speak again - regardless of what the relationship is. Align yourself with compassionate people - you deserve that at the very least.

Robert, people are so narcissistic and self centered now. Don't waste another minute of your time and energy on this person. They probably don't even know what multiple myeloma is. They won't take the time to find out. I am very careful who I talk to about my health now. I hope you feel safe here. Big hugs your way 🤗

Tell them - They should hope they never get to know anything about MM

Robert, my caregiver and I were discussing this just the other day. We came up with this quick response: "Multiple Myeloma doesn't often show on the outside. You do NOT want me to go into detail!" Hypochondria is a very cruel word. Those people who use it don't remotely get our illness, nor how awful it is to tell someone that. It's an insult and they should realize that. By the way, I have all the same symptoms you do, and absolutely not, they are not imagined. And they are very debilitating and limiting. Trust yourself, and try not to be hurt by the ignorance of others. Easier said than done, I know.
