- But then I noticed that while I was thinking that everything was false, it was absolutely necessary that I, who was thinking this, must exist. I realized that the statement I think, therefore I am was so certain and clear that no doubt, no matter how extreme, could undermine it. I concluded that I could accept this as the first principle of the philosophy I was seeking.
- Depression (mood) (Wikipedia)
Depression is a mental state of low mood and aversion to activity. It affects more than 280 million people of all ages (about 3.5% of the global population). Depression affects a person’s thoughts, behavior, feelings, and sense of well-being. Depressed people often experience loss of motivation or interest in, or reduced pleasure or joy from, experiences that would normally bring them pleasure or joy. Depressed mood is a symptom of some mood disorders such as major depressive disorder and dysthymia; it is a normal temporary reaction to life events, such as the loss of a loved one; and it is also a symptom of some physical diseases and a side effect of some drugs and medical treatments. It may feature sadness, difficulty in thinking and concentration and a significant increase or decrease in appetite and time spent sleeping. People experiencing depression may have feelings of dejection or hopelessness and may experience suicidal thoughts. It can either be short term or long term.
