Hi Mud,
Thanks for posting your experiences and let me be the first to say.. hats of for getting your OW and in such a magnificent divespot that the Galapagos Isles are (to be honest they are on the top of my still need to dive list).
On to your issue... I read your experience carefully and in my honest opinion this is a catch 22 situation. Let me try to explain, and please bare with me.
Breathing: When you think about diving and breathing you probably believe that inhaling is the most important part of breathing. This is not the case, the exhale is much more important. When you inhale you oxyginate your blood through your lungs, however you also are removing CO² from your system which has been generated by your metabolism (exhale).
It's this CO² that triggers your breathing reflex and makes you feel out of breath and anxious. (technically the acidic level of your blood which increases by CO² is monitored by your brain, which in turn triggers your breathing).
So let's say you feel a bit stressed or anxious for whatever reason. You start breathing more shallow/harder. You probably are not inhaling more shallow but exhaling more shallow. So you are retaining CO² in your blood. This will trigger your brain to tell you "oh ow out of breath"... causing you to feel more anxious and out of breath even tho you are breathing harder. This added anxiety will cause you to breath even faster and shallower, again more CO² in your system... rinse and repeat... a runaway proces. In the end if you are not aware or a DM / instructor doesn't assist you are going to feel really as if you have no air, while you are doing every effort possible to breath (hyperventilation). French divers have a term for this called "essoufflement".
The only way to get out of this vicious circle is not by breathing more in but by breathing less in and more out. Slowing your breathing down does this naturally that's why the instructor in your first episode tried to calm your breathing.
Anxiety: As already stated by some former posters anxiety is a slippery beast and can be triggered by alot of factors, many of them can be personal. This anxiety can trigger another vicious circle called the panic circle, where in the end you feel so out of control that you can no longer think straight. First of all you need to analyse the trigger that's causing the anxiety and then try to remedy that and this is personnal. I'll give an example:
Getting swept by current causes anxiety, many things can cause anxiety:
Hope this helps.
Cheers

Getting swept by current causes anxiety, many things can cause anxiety:
- Physical exertion: You are not fit enough, or you think through lack of experience you can fight a strong current, triggering shallow breathing Remedy: Get in better shape or know that fighting against current is not possible and try to move across current. Recognise when you get out of breath.
- Feeling out of control: If you've never experienced such current you'll feel out of control, causing stress. Remedy: Get more experience driftdiving.
- Past issues: If you've got bad past experiences with current, the memory of this might cause anxiety Remedy: Try to acknowledge this feeling and know that the memory in itself is causing the stress.
- etc
Hope this helps.
