Zyzal and Azelastine with anxiety?

Hi,

So the last few months I’ve had really bad sinus issues. When it’s bad I feel like my head is about to explode. It’s not sharp pain, it’s just crazy pressure and headaches mainly in my forehead above my eyes.

I went to the doctor today and she prescribed me Azelastine and told me to stop Claritin and switch to Zyzal. I have bad anxiety and my main trigger is definitely my sinuses. when I have sinus pressure it just makes me feel spacey and off. Even when my head doesn’t hurt I still feel like my brain is foggy. It’s really frustrating because I don’t know how to fix it. I’m afraid of taking new meds because I dont want bad psychological side effects. Is this common or has anyone experienced this? I don’t know what to do
