Overnight shift and cortisol testing

Hi all, I'm new here and have a question. I hope I'm posting in the correct section. I recently found out I am hypothyroid after having a TSH of 8.280. I also have chronic fatigue syndrome and fibromyalgia. My doctor wants me to do an AM cortisol test. I work overnight shifts and usually sleep during the day waking up late in the afternoon/evening. How does someone like me do this test? My lab still wants me to come in at 7am but I'm usually still awake from the night at that time on my days off. Are there any other options for this test?
