"Trying to get my medication"

Long story short... been with this practice forever. Past few years tho after having 2 mc which wasn't delt with properly I had a baby, then a few months later I started getting numb feelings in my leg and after falling down stairs I finally went to my doctor to be told it's sciatica threw tablets at me. Then it took for an out of hours doctor to say it's not and referred me to hospital where the 1st doctor examined my leg and knew it was sciatica and sent me for an emergency mri scan.

I found out that my L5 had collapsed onto my S1 and the cartilage was compressed against my left legs nerves which was causing the pain in my legs. I've been put on every tablet possible which never helped or helped for a few hours calming the pain down. I have been referred to the pain clinic and physio but still nothing from them, so I've really just been relying on my medication! Now as it's a repeat I understand I have to give the at least 3 days notice but it's got to the stage I'm having to give them up to 2 weeks notice due to this.... anytime I phone to order my prescription they don't have records of me phoning or if I do I get someone telling me they are highly addictive and shouldn't be on them due to miscarriages. That is none of their business to begin with and made me feel like I was abusing drugs! Or my prescriptions got lost or missplaced or not done now I have complained 3 times now and each letter has never got to them and now they have removed me from my GP which I do currently need as I'm on medication that I have to take continuously. I'm appalled!
