JMHO, and as I am what some consider “old school”, I don’t sugarcoat a response in order to make light of the situation. Step away from the pursuit of getting your OW cert and seriously reflect on why you are doing this. While it is common for some to have apprehensions in the diving process, your reactions in the process are more than expected.My partner has been diving for many years. So we thought it would be fun if I learn as well.
I waited for three years before I decided to start, It was scary, I decided that I did not feel ready yet, feelings of unease, gave me anxiety, psychologically I was slightly freaked out by everything, I found it quite scary, It freaked me out a bit, I felt very uncomfortable, I was scared, shivering and shaking, brain was all foggy and hazed, not think straight and felt dissociated, internally I was quite scared,had a panic attack at home. I cried my eyes out and felt like I never wanted to dive again, My brain simply refused or blocked, not prepared, my internal turmoil, I felt scared, I feel scared, wonder what the next lessons will have in store for me. Are they scarier, my panic 'internal'.
Do you really have a desire to get into diving or are you forcing yourself into an activity because others are pressuring you into something you are obviously uncomfortable with doing. This needs to be an “I“ decision and not a “WE“ decision. I linked your post and only showed your reaction to the experience. You waited three years trying to decide on this hobby so take some more time to figure out if this is for you. Diving has been a large part of my life over the years but my wife has no interest in it and I have never tried to convince her otherwise.
Getting through your OW is just the start and while you can shop around and find an instructor to hand walk you through the process, it’s the anxiety, fears, and your reactions of what happens during a normal dive that may be more concerning. Diving is not for everyone and you need to gauge your own level of safety over what others want you to do. If diving is something you really want to do, you will get through it but just make sure your are doing this for all the right reasons.
