I am under investigation for CFS; my appointment is not until June as there's a long waiting list .
I've been poorly lately with a bad cold and now I am so so exhausted . I can manage an hour or two out of bed and then I am too tired to do anything so go back to bed 
My doctor isn't the most sympathetic and i am sure she thinks I am just lazy 
It has been nine days now and my project manager is expecting me back in this weekend.
If I ask my dr to sign me off will she just laugh me out of her office ? Or am I perfectly reasonable to ask?
What can I ask her to put on my note to make sure the project manager doesn't just think I am lazy too !
