Codeine WD help

Hi, i hope nobody takes this the wrong way because i know this is a small problem compared to what most of you have faced and i am very proud of all of you and have been reading the posts here. I have endometriosis and chronic pain. I started taking opiods in hospital, oxycontin and i quit cold turkey when my condition improved and it was the worst. Ever since then i have had to take opiods regularly but now i am trying to come off completely, not for the first time. I have been taking codeine 30/500 2 pills 4 times a day for probably 6 months now and a short acting opiod for breaktrough pain sometimes. I started reducing the meds and the pain is so bad. I cant sleep because of pain and just lie awake crying or walking around my apartment. Those of you who have chronic pain/mecidal issues how did you cope with the pain? I know opiods make the pain worse when you stop but how long is that period? Im just feeling hopeless because i really want to quit. Again, im sorry if this is offensive to anyone that is not my meaning. My doctor is involved and has given me a tapering plan but the pain is what stops me.
