Well I never thought I would have this problem. This was my 10th dive. We where diving with Scubatek out of Destin, FL. I was all ready for this dive was my first saltwater dive and my deepest dive yet. I jump in the water start to decend. There was a cool little shark watching everyone go down. I was second person on the line going down. At about 20' my new Mares Demon mask is leaky so I clear and contiune the decent. Kept clearing my mask on the way down about every minute. . Got to about 70' cleared mask again and when I opened my eyes I felt confused. I started breathing reall heavy. I finished the decent to 86' then I couldn't slow my breathing down I had just got off the line so I immediatly made it back to the line. MY mind was telling me to surface immediatly. I was in complete panic mode. I was calming my self down thinking alright don't get in a big hurry and don;t go faster than your bubbles just go to the top. so I came up to about 70' got calmed down and though what the hell is wrong with me, then decided to go back down. I went back down and the DM was there he signaled if I was ok. I signaled back that I was not. He grabbed a hold of me and I finished the dive along side of him. This was really an awful feeling. It felt like I was going to die. After the dive I still had this shaky feeling. I have never had anything like this happen. I have done all sorts of things in life that could cause someone to panic but it has never happend to me. I made the next dive (with a differant mask) but was very slow on the decent and had to hang on the line for awhile before swimming off. The panic kept trying to come up and had to take my time to hold it back. This dive was to 70'. After I finalyl got over the panic I felt great better than usual. The dive master left my sdie and Iwas diving along with my wife. We where checking out soem fish and differant things then the DM came back to get us for the accent and as soon as I saw him the panic feeling started coming back. Got back to the rope and made our accent with out any problems. Made 2 more dives this sa,e day to Vortex springs. First dive I as still feeling un-easy dive was at aound 30' depth. Sencond dive at Vortex was better I started relaxing more but still had that feeling deep down in side of me. I can still feel the same panicky feeling now thinking about diving. I already have a Costa Rica trip planned for November and I really want to be able to get past this. I am planning on diving the next few weekends to see if I can get comfortable again. I am very thankful for the DM at Scubatek. His name was "Sharky" if not for him and my wifes encouragment I don't know if I would have made the second dive. Which was great once I got comfortable. he did a great job staying by me helping me get comfortable in the water. This thread almost describes the exact thing that I felt. http://www.scubaboard.com/forums/ne...ed-panic-attack-100-feet-lessons-learned.html Has anyone else had this problem and how do you get past this. It was an awful feeling I can now see how people can die from panic. Your mind is trying to tell you to take off all your gear and just rush for the surface. It doesn't even make sence to me that this would happen, especially to me. I never had any hessitation about diving or anything else. I am just glad that I held it together and didn't run for the surface or do anything stupid. I am wondering if perhapse being narced played into this once at depth from my heavy breathing because I do not remember coming off the line on that first dive after I came back down. I remember looking down at the bottom through my watery mask and feeling panicked again and I remember tapping the DM to tell him that I was not ok and grabbing hold of his bc. Then I was just consentrating on staying calm. I don't know if I was thinking that water was about to start coming in my reg or something but I was defiantly not comfortable. It is very weird to me. Any help would be appreciated.
