Panic attack or something else?

I'm a 19 year old female and I was diagnosed with Bipolar Disorder type 2 about a year ago. Last night I went to sleep around 3 am, was half asleep for 3 hours tossing and turning. Felt like the bed was trying to swallow me and I woke up drenched in sweat and breathing hard. It took me over an hour to calm down because it was almost like I was hyperventilating. I just couldn't breathe. I'm just confused as to what happened. Was this a panic attack?
