It is impossible to be grateful and unhappy at the same time. Choosing one of these emotions makes it impossible to feel the other. “Grateful” and “unhappy” literally can’t occupy the same space at the same time.
You have to choose between being grateful or being depressed, too. These emotions are so far apart that from one pole the opposite pole is not accessible to you. Being “grateful” and “depressed” are mutually exclusive emotional states.
If you are occupying the feeling of thankfulness, you can’t also occupy the feeling of anger. When you are angry, you are occupying the emotion of fear and the state of need. Thankfulness is not a place of wanting. Thankfulness is a place of abundance.
Gratitude is too big to share space with any other state. It literally crowds out all negative emotions. It pushes fear, anger, and sadness out if its way, and it consumes all of your emotional real estate.
What are you grateful for right now? What should you be even more grateful for now?
