Basic background: A large tumour was picked up on by an out-of-hours GP in April this year. I got told I probably had cancer. It took me 15 weeks to see a consultant, after being referred to the wrong consultant who promptly lost my notes. I got given 3 different diagnoses, one of which gave me less than a year to live. It took until September to actually have the operation, after which I didn't have adequate pain relief and got sent home with an insufficient supply to last me until the follow-up appointment. I didn't get a full diagnosis until 3 weeks after the appointment. I got referred on to another consultant after I had complications post-surgery. Hospital lost my notes but they were subsequently found. I asked for a second opinion, which I've had today, only to find that the hospital didn't pass on my test results or my notes so the consultant I saw didn't have enough information to make a diagnosis. I now have to wait 6 weeks for another appointment while they find my notes and test results. The second opinion consultant does surgery at the other consultant's hospital so she said she will consult with the first one about my case history the original diagnosis of the cause of the complication, which I've challenged.
So I've complained that the second opinion is clearly not going to be independent, will complain about them not being prepared for the consultation today, will complain that these constant mess-ups are seriously affecting my quality of life and mental health, am seeing my GP today about being referred to someone who is actually going to give me an independent 2nd opinion and am generally so angry that I feel like hitting something.
DH says I should be grateful that I'm alive. 
AIBU?
