Stay at it man - Fill those lungs up with air and release slowly... Sometimes I'll take 45-60 seconds during the day to just - be - and relax my body, mind, and regroup..
Breathing is really an incredible aid to relaxation, stress relief, meditation, calling anxiety, and on and on...
The craziest thing to me is that most human beings in general probably never really pay it any mind during the course if their life since we all breathe every moment of our existence and it's just one of those things that become natural oversight...
