Anti anxiety med issue. These medicines?

I've celiac disease, fibromyalgia and (IIH suspect), I have had tachycardia and shortness of breath issues, I was given beta blockers and anti anxiety for that tho I never had anxiety issues, beta blockers go fine for me but as I take anti anxiety, I get anxiety, my chest feels heavy and i can't breathe, last night I missed my anti anxiety dose, i had insomnia whole night, and every lil noise was making my heart race, and I couldn't stop my mind, this is the first time I felt how anxiety would feel like, I never had this feeling before anti anxiety medicines and I want to get off them, I don't want to make myself this sensitive cause I know I never had anxiety issues in past but no docs believe it how can I eliminate these medicines?
