Thank you for explaining about cortisol and hydrocortisone. I thought hydrocortisone was a topical medication for other ailments. I suggest you ask the prescribing physician or maybe the pharmacist to clarify the dose instructions specifically the quantity and time to take it.
Regarding hypoglycemia (low blood sugar), it can be a common occurrence during times of stress, anxiety, other illnesses or injuries. Could you talk to your provider about this? What are you doing to treat these symptoms? Perhaps your provider can make some suggestions.
