Suggest Treatment For Fatigue And Sleep Apnea

I feel like I can't take a deep breath sometimes it feels like fluid is going into my lungs, I want to sleep a lot sometime for days, I'm week fatigued, this has been going on for almost 2 years now but all test results are normal. It takes a long time for my body to heal and I barely make saliva. I'm on Prozac verapamil tri/HCTZ Prilosec sometimes xanax. Last night when I flossed my gums bleed bad. I have sleep apnea and use cpap machine. And I'm scheduled for a hysterectomy on the 5th of Jan. But I feel that my body is not up to it. Also they are watching a non malignant looking growth on my left adrenal gland.
