Sort to hear of your bereavements.
Well those results will scare you- they are as much use as a chocolate fire guard. I agree with human bean you should have been tested for an adrenal stress profile which measure cortisol and dhea( even more important and more likely life threatening is Addisons- low dhea)
The idea is to measure both over a 24 hour time period. A normal result should show a clear diurnal variation with within range but higher levels of both in the morning and declining thro the day - the lowest at midnight. I when there is unremitting stress which could be infectious, nutritional, allergic, toxic or physical/ mental stress and low thyroid etc the gland starts to become exhausted.All well documented by physiologist Dr Hans Selye.
Most gps pick up on cortisol but if you read www. Drsarahmyhill.co.uk and search adrenal stress you will see there are only so many combinations you can have. But you need both testing. Low dhea affects cortisol balance- which is easily fixed and you need to know when in the day or night your cortisol is high. It could be something as easy as hypoglycaemia.( on the web page)
Higher is more difficult to control but in the meantime you need the range and what that figure actually is. I've seen many test results but not in that format.
Yes holy basil is v good and tulsi tea won't harm you but I'd take nothing until you know more.
Just a suggestion but diet vitamin and thyroid testing is key. I'd suggest you ask for a more detailed stress profile test. Happy to help more when you know specifics. If you have time for Pilates or meditation it's helpful.
Good luck I hope you get the answers you need.
