Anxiety is very common with BP. If nothing else, other symptoms and trying to manage them is enough to make us anxious!

Paranoia is a type of delusion but also a BP symptom; not as common but not rare either. It is currently one of the criteria for a BP I dx, though who knows what will happen with the next version of the DSM...

Definitely take Miss Laura's suggestion to mention this to your docs. There may be meds that can help, and if you see a therapist, they can probably help you work on some strategies for paranoia and anxiety.

You're definitely not alone in this!
