Thanks for the reply suzi.
I have been on holiday recently where I drank far too much which probably explains why I feel worse. I would say I eat OK, but I probably don't eat as much as I should (because I am vain and worried about weight gain). I do not do much formal excercise but cycle a lot through london for work. I am going to try and get back into the gym starting tomorrow.
I haven't seen the doctor. I am very unsure about taking meds and I am sure they will offer them. Either that or they will refer me to NHS therapy which in my experience is incredibly long winded and not very helpful....
