I can't sleep with the cpap machine

I am just beginning my journey. I have my orientation next week. I have had a cpap machine for 2 years but I can't use it. I just can't sleep with something on my face, fighting with the hose etc. I have read that they will make me do another test and use my machine continually for 6 months to a year before moving forward. I am freaked out by this and very discouraged. I move in bed a lot due to chronic hip pain. I have tried different types of masks/nasal pillows etc--it doesn't matter. At times I feel like I can't breathe at all --claustraphobic-like. Has anyone had this issue and they didn't insist you do it anyway? My surgery is in Hamilton Ontario. I don't know if this site is primarily American or not so things will be different between how the 2 countries do things.

I can't sleep with it either... it is terrible
