It is our thoughts about low moods that can make them seem really awful. Patiently wait for the mood to pass. A quiet mind is the best cure for a low mood. Quiet is listening without judgment. Sometimes the simple realization that it is just a mood, will be enough to immediately raise your level of consciousness.
Conscious gratitude can help in altering a bad mood.
Just my appreciating your health, talents, children or simply a beautiful object, you begin to want to give rather than receive. Expecting something back is manipulative, conditional giving. When I love, we should notice differences and see them as interesting and endearing rather than ignore them. By respecting differences, we all have the ability to be compatible. Like many myths, this is just not so.
