Greetings ascully88 I have a question for you, "Why do you want to dive?".
If you are putting yourself through so much stress why is it important to you?
I am agreement here, and wanted to add a little bit. If your only reason for diving is because someone else wants you to, or because you want to overcome a fear, quit now. Diving requires that you will be in control of yourself at all times. Most good experienced divers will tell you that if they are having an off day, they simply don't dive that day. If you are always going to be afraid, you will never be able to dive safely. The only way you will overcome your fears and anxiety is if you are motivated by a real desire to dive.
Now, assuming you really want to dive, I have a tip for mask clearing. You do not have to clear your mask in one breath. Actually trying not to clear in one breath will drive this home. Just press the mask to your forhead, look up a little bit, and breath in through your mouth, and out through your nose. At first, don't breath out completely. Leave your lungs 3/4 full, and take your next breath. Then clear a little bit more. Once you get the hang of this, start taking deeper breaths. The point is that if you try to clear in one big breath, there will be a tendancy to breath in through your nose a little once your lungs are empty. If the water isn't all clear, you will get it up your nose, and tend to panic. Also, remember that a flooded mask is not an emergency, but an inconvenience. Even if you take 5 minutes to clear it, you will not be in any danger. In the spirt of that, you can try opening your eyes as well so that you aren't completely blind to what is going on around you. This, of course, depends on how chlorinated the pool is.
