I've been on citalopram for anxiety for about a year and a half, I suppose it helped for the first year roughly but recently I've started to struggle badly again with anxiety. 

Ive recently started seeing a therapist but struggle to be open because I get so anxious. Constantly feeling tense, fast heart rate and breathing and struggling to talk loud enough. This is making it difficult to progress with my therapist. 

I was wondering if beta blockers would be helpful in this situation to control the symptoms of my anxiety. Thanks
