@MJS1946 - please don't seriously think about throwing in the towel! Take a look at the number of dives these folks have logged since their first training incidents. I'm near 250 now - and the only real 'panic' moment I had after training came about from stressing over a too-tight 8/7 semi-dry suit that was hard to get on (and I haven't worn since - anyone want to buy it? It's a size 4 and I'll never fit into again anyway!!)
I do want to give you one quick word (ok, words) of advice. When we inhale we physiologically send our bodies the message to prepare for action (and your heart rate increases). When we exhale we physiologically send our bodies the message that it's ok to relax (and your heart rate decreases). This is why, in yoga, they have you focus on the out-breath. If you're feeling stressed/panicky, take a moment to empty your lungs (getting rid of the carbon monoxide) and then take a healthy in-breath to fill your lungs with oxygen-rich air. Your brain will thank you as you'll be able to think more clearly. Just the act of doing this will help to regulate your system as you focus on something other than your anxiety. Once your mind is refocused you will find that you still have a regulator in your mouth and that all the next 'right' things will be there for you to do.
