Dear MC,
There's something I need to bring up tomorrow that I'm scared to bring up. Please don't freak out or anything. I think it's probably a side effect of my new medication. I know it's something I should talk to p-doc or individual T about, but I don't see them till Fri. and Wed., and I see you tomorrow. If you could just maybe reassure me that everything will be OK? (Also, don't have reason to cancel!)
