Silver... I totally paniced when I swam in a wetsuit for the first time.
This is coming from a gal who was a competitive swimer... and someone who LOVES open water swimming. I have never had issues in OW. Seriously.
The race I did with a wetsuit, was horrible. I had a great swim... but I do not clue HOW. I felt like I couldn't breathe the whole time. I hated that stinking wetsuit being on me.
I basically had my mind take over... and I told myself that I COULD breathe... I was doing fine... and to do what I do in the pool... stroke-stroke-stroke. It worked.
So, keep swimming in it... it should get better. Good luck!
