It depends on how bad I'm feeling. I'll go see my therapist with a runny nose or a somewhat annoying cough, but if I'm using a pack of tissues per hour or more and if I can barely talk and I'm so sick I can't sleep, then I don't go to session. I normally get very mild colds, but sometimes I can get them really bad (without fever but it feels like i have fever) and when that happens I stay home as much as possible. I remember the last time I had a cold it was awful, I canceled therapy and took a week off, then after a week I decided to resume all my activities (therapy included) but my cold was just better and it didn't really heal for a couple of weeks. That one was nasty.
