You used to enjoy reading, now you no longer do. There is now almost nothing that gives you pleasure and the sense of happiness. You are almost always in a low mood and constantly worried about something. You have very low self esteem. These are signs of depression. Depression can be a serious mental illness. This condition causes disturbance in your daily life and when it becomes severe; it would disrupt and destroy your life.
Depression occurs when the chemical serotonin decreases in the brain. Serotonin regulates emotion, body temperature, hormone levels, sleep pattern as well as blood pressure. When serotonin levels are low the brain cannot function optimally.
The following are the common clinical signs of depression (symptoms include):

- Easily irritable and annoyed. You get easily ticked off and sometimes at no apparent reason. Even attempts at making yourself happy annoy you.
- Feeling of worthlessness, guilt and even self-hatred. You keep on being worried about everything. Small issues seems big to you. When things go wrong, you blame yourself, you feel guilty of everything.
- Insomnia. This is a vicious cycle. The more you try to sleep, the more disturbed you become and sleep avoid you. Lack of sleep makes you even more irritable. You would also feel lethargic all the time, with a monster headache to boot. When everyone is asleep at nite, the feeling of loneliness would give way to feelings of hopelessness and despair.
- Poor concentration and memory. The lack of sleep and irritability will cause you to have poor concentration and poor memory. You would tend to forget things, even routine stuff.
- Feeling of restlessness. Without knowing exactly why, you constantly worry about nothing in particular.
