Could it be anxiety or asthma but latley its hard to catch a breathe i yawn to do it also my nose is swelled and red?

You do not have asthma. You have bad rhinitis so you can't inhale through your nose effectively and you inhale mainly by mouth during yawning. You should use nasal steroid OTC, nasacort or nasonex twice a day + nasal saline 3-4 times/day in btwn +/- allegra or zyrtec. Practice deep breathing technique (in by nose 2 secs, hold 4 secs, out by mouth 6 secs) if you have history of anxiety disorder.
