Hi, I am your run of the mill vacation diver, SSI advanced open water license with about 25-28 dives, not sure exactly without checking. I used to have absolutely no issue with diving. I actually once became sick with dengue fever underwater while diving, and despite feeling bad, went back in tired and did not have any issue with the dive at all (was the last dive of my AOW and my instructor kind of pressured me).
However, two years ago, on Koh Tao, where I have dived many times before, I kind of felt especially fatigued, but made the mistake to go into the water. I Believe I was fatigued from a dive we made on the very previous day. Before jumping in, on board, I already had the feeling like I could not breath properly through the regulator. I hoped - big mistake - it would get better when I was underwater, but it did not. So I told my instructor on the surface I was attempting to dive, but that I might have issues so he should not be surprised if I have to go back up. Then we started the dive, I quickly had trouble breathing and went up again. We then took another attempt, very slowly, where I used the anchor robe to slowly descend. However, at about 5 m, I still felt like I could not breath properly, but this time, I panicked a little and went up immediately.
Ever since, when I go into the water, I get some anxiety about diving and that I can not breath properly. Mind you, this is completely psychologically. For example, I tried to dive a few times in Indonesia last year, but had some issues every single time. On one dive, the initial descend was okayish, but at about 10 m maybe, my fear started to return and I signaled this the instructor (I briefed him on my situation beforehand). We shortly tried to continue the dive, but I felt like the fear was getting too much. I signaled him I want to abort the dive, and as I said that and we got ready to ascend, I felt my fear completely vanishing. I then signaled to I'd try to continue and was able to finish the dive by holding the hand of the instructor and of my girlfriend most of the time.
While I am not a scuba addict, I like to do it occasionally and would love to dive again with my girlfriend. Do you have tips to overcome this fear? Did you have such fears before and overcame it?
