I am going on vacation next year and have been looking into scuba diving.  Found out that its underwater diving that uses a breathing apparatus to breathe underwater.  Not too sure if I want to or not.
I think scuba diving is so fun! It is a magical experience.
Oh good, so you know more about it than me.  I know that you carry your own compressed air breathing gas to have free movement in the water but I'm worried about getting anxious under the water.
I got pretty anxious when I went. I felt like I was suffocating every time I went under, but after attempting it numerous times, I was able to calm down and go.
I am looking into take multiple classes until I feel better about it but nothing matches the point where you have a shark swim by and you hyperventilate. ha ha. They also offer surface-supplied diving with the breathing gas on the boat but that doesn't seem much better or maybe worse. 
I did not see any sharks, but I did see a very suspicious looking fish that was larger than me and the only thing that made me panic was that I could not talk underwater to ask someone what it was.
Diving safety
The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short term survival. Other equipment allows the diver to operate in relative comfort and efficiency. The performance of
Scuba diving
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a new mixture called enriched air (Nitrox) has been gaining popularity due to
