Welcome to BipolarLand!
Nah, you ain't got it. Just that it's happened to me one or 168x before! Worst feeling. The only way I've ever been able to describe it to people is by asking them this:
"You know that feeling you get when on a roller coaster, or water ride, and you're slowly going up that incline, seeing the top of the world, knowing you're about to go screaming down full speed on the other side!" that's normal, that's adrenaline running in our systems, and it feels good!
But when woken up out of a dead sleep, at 3am, for some unknown reason - that adrenaline no longer feels very good. Now it feels like you're out of control, something is wrong with you.
Try and repeat and believe and convince yourself that's all it is, just adrenaline and anxiety, and you can easily beat it!
That is NOT to say that you shouldn't get checked out, that of course never hurts and should be your primary person if this is all new to you.
Them Oxycodone's are a life saver, but also made me feel crazy at times. If I ate too many, which was all the time, it gave me sleep issues. But I didn't care, because if I woke early and couldn't sleep, I would pour myself a coffee and then take another oxy! But I also found out the hard way about sleeping issues and other issues when running out of them, or when it came time to stop using them altogether.
