I never found any breathing exercises that helpful until I was taught one that I felt really put me in control. It is called 'The Divided Breath' and I will post it for you, along with some other links that you may find helpful. Remember to practice daily, even if you are not feeling anxious. It is the deep, slow breathing habit that you want to develop, and it takes some time for it to become second nature.

Okay, my favorite is this one, it takes some practice though. When I first started, I could hardly do one!
The Divided Breath:
Imagine your lungs as having 3 parts. The bottome third, the middle, and top third. On the inhale fill the bottom third first, then the middle and finally the third. Make sure that this is one continuous breath, but divided, with a slight pause in between each third. Hold the breath in for 3-5 seconds if possible. Exhale in reverse. First blow out the top third, then the middle, and finally the bottom third of your lungs until all air is expelled. (remember the pauses) Repeat several rounds for a toatal of about 10 minutes. Practicing this every day will not only give you control and structure to your breathing, it will strengthen and loosen the thoractic muscles, allowing better, more productive breathing, and relieving the chest tightness!
