Seems from my research that the paranoia is very common with bp. My DH thought I was trying to put pills in his soda.
It's something you need to let whom ever perscribes your meds know that way they can keep an eye on it and/or fiddle with your meds to get something that helps more.
Remember meds for this are a trial & error, hit & miss type thing. Eventually you will find the perfect combintaion for you. Good luck
