I've had a couple of stress induced hallucinations so I imagine that you could indeed have stress induced paranoia as well. I know you're really worried about being able to keep up the facade when you are away with your parents. The anxiety must be making you quite uncomfortable. Of course you could also be in a hypomania - you said it yourself, it's difficult for you to recognize your own mood states.

As for dealing with drug side effects, I must take cogentin with most antipsychotics to combat stiffness, restlessness, etcetera. It sucks having to take another med to balance out the first med but that's what I have to do. I know you hate medication and I'm so happy you're taking the Seroquel in the first place. Cogentin might help with restlessness if it is from the med and not from hypomania. But that's totally up to you.

I hope things calm down for you soon. I can't tell you not to worry about your upcoming trip but just know I'm sending positive energy out in the universe for you.
