Hi there I to take a beta blocker..have now for 4 months but I still get pains in my chest I have had all the tests to make sure my hearts fine. I also take it for high blood pressure....so I am hoping in time these pains will stop it worries me sometimes because I think this is not right I should not have pain in my chest. I also take zoloft and I have to say I feel pretty good I still get that odd feeling now and then my mind gets scared so thats when I do yoga. I really don't focus to much on my breathing because I simply can't my mind always wanders. I will be doing a yoga move and I'm thinking about something else entirely different like a conversation I had yesterday but the act of doing yoga and all the stretching makes my body feel better and before you know it 45 minutes has gone by. I can't sit quietly and relax I agree to focus on my breathing caused me to actually hyperventilate....it's weird how things work but it works for me I just say a prayer for everyone who has to live with anxiety it can be so scary
