It is important to remember that we all go through low moments, that disappointments, sadness, apathy are also a normal part of some moments of our lives. We should suspect depression when several of the symptoms that we are going to describe are seen at the same time, when they persist for several weeks, when they seriously affect and prevent or make it difficult to lead a normal life. The main warning signs that you may be entering a depression are the following:

1. 1. Feeling down or empty. Continuously being sad, anxious, in low spirits, or feeling empty. These are things that happen to all of us one day or another, but if it is something continuous, persistent, it is a worrying sign. There are those who experience a mixture of the terms that I have described, others would identify with only one of them.
3. 2. Loss of interest in everything. Depression generates a feeling that life has no meaning or value, that there is nothing interesting in it. Attitudes of criticism of everything, of boredom above all, of a cynical consideration of one's own life and the lives of others are a typical framework of depression. The loss of interest can also affect the most beloved “hobbies”, the things that we liked the most and even our sexual life, which can generate tension in personal relationships and reinforce depression.
5. 3. Lethargy, fatigue, or a feeling of not having energy. People at the beginning of a depression may feel that they have no strength at all, it may be difficult for them to get out of bed, they feel exhausted by the simplest domestic tasks, they cannot face any of the tasks they carried out every day, in work, at home, in everyday life.

• 4. Changes in sleep pattern. Very often people who are entering a depression suffer alterations in the number of hours they sleep. They may suffer from insomnia, sleeping much less, having irregular sleep and waking up too early and being unable to go back to sleep.

Crying is a healthy and natural emotional expression. However, when depression exists, the person tends to cry more than normal, frequently and for most of the time. Sometimes crying can appear for no apparent reason or reason. Likewise, a deep feeling of sadness is usually experienced.
