"If I go elsewhere it will mean starting again"

I attended the gynaecological clinic in April 2015 I was miss diagnosed with two gynaecological problems on the visit and was told I need physio treatment. I paid for a private consultation and was found to have a prolaps. I have waited since December 2014 for an appointment which after not being able to attend due to ill health and a cancellation by the hospital I was finally seen April but as yet have only just had my first physio appointment last week and am still waiting for a clinical appointment at the Vulva clinic which I have for September but as I cannot attend at 6. pm on that day I have been told to go back to my GP and ask to be sent elsewhere. I have waited 12 weeks already it would mean starting all over again.
