had to call in sick to work today. First day I've missed since starting the job 10 months ago. But I always feel guilty for some reason. I wasn't deathly ill I just woke up with a splitting migraine and had a headache all throughout the night which led to minimal amounts of sleep and couldn't imagine performing my job duties with the type of headache I had. Still I hate the feeling of guilt. I at least have sick days saved up since I never use them.
