It seems that no one likes sorrow since it shows one's weakness, and being angry is "better" than being sad. Paradoxically, sorrow makes us stronger. It slows us down, and it is needed, like sleeping, another kind of slowing down, after the whole day and evening awake. Sorrow comes with stress when something bright disappears from life. Almost each sphere is put on pause to give you time to recover and reflect. Sorrow helps ask the question, "What do I need to be happy?" and enhances the accuracy of judgment.
Sorrow is one of the continuous emotions that includes stages of protest, humility, and helplessness. If one stifles sadness and does not allow himself to live through it, the chances of psychological disorders and instability increase. And on the other side, age or relationship crises, for example, are overcome thanks to sorrow. If you have problems but pretend it's fine and try to smile, you will be stuck in your current psychological age and unable to go through a crisis.
Make notes on how to experience sorrow. Take a break first; allow yourself to cry and thereby provoke the organism to synthesize the endorphin hormone. It reduces pain and relaxes. And everybody knows the person who will always love you, spend sad and happy days with you, and comfort you 24/7. It's you, so get the warmest Ikea blanket, the tastiest hot tea, and watch the drama "A Dog's Purpose" to feel all the sadness in the world. After all, they say that happiness wouldn't exist without sorrow.
