Why Do I Fall Asleep Without Knowing, Why Are My

Why do i fall asleep without knowing, Why are my cheeks always red and I also get a warm to hot sensation in my left ear nearly every day. I have sleep apnea and am on a cpap. I sleep 5-7 hours straight so im not sure whats going on. I also have little energy throughout the day. No motivation, im forgetting things, names, words and to many thoughts racing. I cant focus on one thing and see it all the way through. Im bored easy. I never do anything for enjoyment anymore. Im pretty much a homebody and loner. Can you help me figure out whats wtong with me?
