Are you aware of your breath? Through your nose, breathe in and count to 4 while letting the air fill your throat, lungs and stomach 1, 2, 3, 4 and then breathe out letting the air flow out in reverse 4, 3, 2, 1.
Yoga is teaching me how to breathe properly again and I do actually find it challenging. When I am learning a new asana (pose) or doing something a little more difficult, I find that I hold my breath instead of continuing to breathe. When I am aware of my breath and do not hold on to it, I realise how much easier it is to go into a pose and how much deeper I can stretch.
I used to suffer from crippling anxiety "nervosa" and was prescribed valium and dex-amphetamines as a teenager. Not recommended by the way. No child should be given behavioural drugs when they are developing! Anyway, I finally learnt that breathing was the key when I started to panic (oh yeah, and eating breakfast...regularly!!). I had to take myself out of the situation until the feeling had passed and just breathe. Maybe that's why I am so drawn to yoga.
