Agree with the above. Find a new GP as soon as you can and ask for a referral. Some clinics require the referral first, some let you book first. I originally was a patient at Fert North and think I was able to make an appt before getting a referral letter but when I switched to FSWA (won't go into reasons here but was very unhappy with FN so changed doctors) they required that my GP fax a referral through, then they called me to book an appointment. But getting into things sooner rather than later with a FS is going to benefit you much more than waiting for your GP, even if the FS says you need to lose more weight at least you'll know.
