"Horrendous hospital avoid in anyway you can"

After falling ill in October 2013 with severe abdominal and back pain I was taken by ambulance to a&e where I was then admited to a ward to be told I had arthritis in my back and the abdominal pains would go in time , I was then sent home only to be taken straight back in within days , I was admited again however as there was a bed shortage I was put on a heart ward drugged up and left for 3 days without seeing any doctors, I then decided to discharge myself as I was made to feel like a strain on resources. After several trips to my GP and constants referrals to derriford in April 2014 I finally get a diagnosis and am told I need an hysterectomy and needed it within 12 weeks , i then had a pre op in May 2014 (after chasing it up) after not hearing anything I decided to chase up operation date to be told I'm on the list, I then get an appointment to see the consultant again (august2014) to be told that a years worth of my notes have been lost but not to worry I'll get an operation date within two weeks , after complaining and chasing I finally got a date for the 7th October 2014 , I arrived on the ward at 7am as instructed I seen all the consultants etc that I needed to see was given my pre meds and got changed to be told at 12.30pm that they had no beds and are cancelling my operation, I have constantly been chasing up another date to be told that I will get a date within 28days however that could also be cancelled and they can not give me a definite answer on an operation date, my GP would like me to go on morphine for the constant pain I'm in but I have young children that rely on me , all I get from the hospital is 'it's unfortunate but these things happen '! I have complained through pals but haven't got anywhere .
