Were you unhappy before you started reading the coffeeroom?
I googled “does internet usage cause depression?”. It seems that numerous studies show that it does.
newcommer: Try mindfulness exercises. When you do things, pay close attention to what you are doing (like doing dishes or folding laundry, or even when you are getting dressed.) When you do these things, don’t think about the past. Don’t think about the future. Just pay close attention to what is going on in the present moment. It may be difficult at first, but if you keep trying, it will do wonders.
And like others said, it’s important to figure out what it is that is disturbing you. Some things are obviously beyond our control. Some people live with others who cause them to be depressed. And one must learn how to live with that without it bringing them down. Sometimes a person’s own belief system causes them to bring depressed, when in reality they have a belief that is all wrong.
