person A: I've got a health check coming up tomorrow_comma_ but I am a bit nervous about it.
person B: I never liked those either.  Do you have any health problems that would make you dread it?  
person A: Not really (I think). Just the whole process is something that makes me nervous_comma_ perhaps foolishly.
person B: Don't sweat it.  You'll do great.  Its never a fun process but that's so good you're keeping up with your health!
