<human>: Can you give me a shortened version of the text?

We've known each other for about 6 years now.

I've had epilepsy for over 2 years now and it's pretty bad; if I average out my recent episodes I'm having about 8 seizures a day.  I've had 55 in the past week.

This man, an older man, takes every opportunity he can to console me by relating his experience with asthma, and how hard it was and how he miraculously got better.  I think he's trying to make me feel better; he'll say things like "I know what you're going through."  For one, I don't think he **does** know what I'm going through, and more to the point, even if he did I am not comforted by his comparing my hardships with his.  I am also not comforted by him telling me that his asthma eventually just went away, cleared itself up miraculously, because what am I supposed to do with that?  Be happy for him?  Keep hoping the same will happen to me?

His intentions are totally pure, I'm sure of it, but this man is just generally lacking in tact and judgment (also evidenced by other interactions we've had over the past couple of years).  He's also kind of self-important and I think that's why he likes to make it about himself.

**Anyway**, the point of all this is to wonder how I can tell this man to stop trying to make me feel better.  I want to do it RESPECTFULLY and TACTFULLY so no advice please that I just tell him to sod off.  I do actually want to keep the relationship afterwards.

If he wants to give me sympathy, fine; it's welcome but I'm not demanding it from him or anybody.  It just irritates me that he makes it about himself and doesn't actually sympathize with me.
<bot>: Colleague essentially tells me, "I know what you're going through because I've had hardships too."  How can I TACTFULLY tell him to stop?
