How am I'm supposed to breath?

We all know we need our "air" to breath. Well why is it that our "air" seems like it runs out and makes it hard for us to breath? As far myself, I've had to adjust to my "air" and it's changes many a times. This last adjustment was big though. I mean, the "air" was just at a constant flow... it was great. I remember when I met it's quality and pureness.. it was almost like this "air" was especially made for me. However, the time came for me to leave the region in which this "air" was native to. I tried my best to bottle it and take it along, even tried to import it... but it became more and more scarce, until I was to the point where I couldn't breath again.... I'd only get enough to take a full breath and that had to last me until the next breath. It was hard, and getting worse... Finally, I stopped trying to breath and just breathed.... I wouldn't say a new "air", but just my own source of air.
If you take nothing else from this at least take this... Always remember, life will give as well as take things from you. You must love who you are and be confident in you because in the end, you're the one who has to be happy with you.

"Air" will always be there for you to breathe,
