I seem to have this to varying degrees, usually only lasts a few minutes usually on the descent and mostly consists of a few thoughts along the lines of 'what the hell am I doing here' and then it passes, quickly forgotten about and I really enjoy the dives. Last week at dozzi was a first for me in that I didn't have any at all. Yesterday first dive dropping down on the stanegarth it was quite severe, had a fairly slow descent waiting for the rest of the group who have the odd issue with equalising - but my anxiety lasted down to last few metres above the stern - then quickly forgotten -to the point where I only remembered it today. At the time however the only I can compare with was when I nearly quit on my first pool dive and it has never been quite like it since. I just can't put my finger on why? Is this unusual?
