One of the most valuable practices we can engage ourselves in is not taking on the energy of others.
By working on developing our own sense of wellness, balance, joy, and ease we are able to learn how to carry it with us wherever we go and not be swept up by the stressful, anxious, angry, sad, and unhealthy energies, words and actions of others.
Keep sitting. Keep breathing. Keep smiling. The fruits of the practice will reveal themselves in time.
