"I had so much respect for my GP"

I have been suffering from severely bad periods for the last 1 and half years now maybe longer I've lost track of how long this problem has actually gone on. I have been going to my gp every other week due to severe pain and black clots during periods. This has been brought to my gps(also family planning Dr) attention from atleast October 2018 who said they wanted to refer me to the gynecologist.

I waited and waited and was assured that I had been referred and it was a long waiting list which I replied every time with no worries. After a recent investigation it turns out that I wasn't referred to see the gynecologist until September 2019  which took me back - my gp had not been telling me the truth this whole time. I thought I was being paranoid because I am an over thinker which the gp themselves had commented on. I trusted my dr.

I have been on hormones, bloods taken, antibiotics. I also suffer from severe anxiety and depression and severe pain in hips and back which all get worse when my period is due and during. My last appointment I had a medication increase for anxiety and I am on a range on pain killers which should be monitored every 4 weeks I cant get an appt. I get calls back at 530-6pm just before the practice shuts and don't get seen when I have requested an emergency appointment. I need to see a copy of my medical records and it seems to move practice? Does anyone have advice regarding what I can do. This is only a small part of the situation there has been other incidents. I am gutted that this has happened I had so much respect for my gp and I feel so betrayed.
