I can't seem to stop sleeping so much. I'm pretty sure I have sleep apnea?

I have literally stayed in bed sleeping for 8-9 hours straight. Then I would wake up, do something so simple, and then feel extremely tired all over again. Like today, I've been sleeping off and on while on GAG... phone falling on my face like three times already (obviously I'm still laying down in my bed). I don't know what's going on. I could literally sleep for a whole day, then if I do something as simple as walk downstairs and back up, I'll get sleepy all over again.
Help :(
