Just to update:

I have made some progress although it has not been easy.

I had my blood tests done for minerals, vitamins and sex hormones on Wednesday. I should hear back about the results of them on Tuesday with a doctor. I have not heard anything about them so I presume I will need to wait until the appointment.

I spoke to my endocrinologist's secretary. I have not been referred to a gastroscopy as I had thought because a test I had done for coeliac disease back in January was negative. The endocrinologist tried to make this clear in the letter I received, for my doctor to read, but the doctor misread the letter and thought I was still having a gastroscopy done. All this confusion upset me and made me cry. I don't know why that happened. I think it just expressed my feelings in wanting to get well enough to get back out into work and with every delay or bit of confusion, that seems like that prospect is getting further and further away from me.
