There are a few things to remember when diving, but the most important thing is to stay calm and keep breathing. When you are diving, you are underwater and it can be easy to get overwhelmed and start to panic. If you start to panic, it will be hard to think clearly and you could put yourself in danger. So, if you feel yourself starting to freak out, take a few deep breaths and try to relax. Remember that you are in control and you can handle this.
