hi friend it makes me very happy to read about how Buddhism has helped you so much however, about the breathing, it does not form the foundation for all of the teachings and types of Buddhism awareness of breathing is a very subtle practise and it is the result (rather than foundation) of applying the more subtle teachings of Buddhism, such as making the mind still by letting go of desires and judgements in the Buddhist scriptures, we will find the Buddha did not teach awareness of breathing to all people the Buddha generally only taught awareness of breathing to his monks & nuns and those that were very serious about higher training to most people, the Buddha taught them to practise things such as generosity, gratitude, self-love, non-harming, good karma, trust in the infinite compassion & kindness of the Buddha, etc again, it makes me very happy to hear about how Buddhism has helped you so much i can only recommend you continue to practise the parts of Buddhism that have been proven to help you warm regards element
