Sleep Apnea Treatment

On the Onset of sleeping just as I hit the sleep mode when im unaware that im asleep i hop up out my bed gasping for air with a flutter in my chest then a little afterward I get chest pains.

I took ekg ecg and blood flow test everything normal and i also took too sleep apnea test that were normal but why do i still get these things?

I am using CPAP and sleep,depressin and anexity medicines, but rresults are not encouraging

Lately, I can’t fall asleep, I’ll lay in bed for hours with the lights off, trying to sleep. When/if I do finally fall asleep, it’s a very restless sleep and I wake up easily or I have terrifying dreams that wake me up. I also get terrible headaches in my sleep.
Do you know what this might be? And is it serious enough that I should see a doctor? If I don’t need a doctor, what are some home-made things that I could do?
All answers are GREATLY appreciated!
