Sadness and darkness are natural cousins. Since ancient times, people have worn black to express their grief. Happiness is attracted to sunshine and depression to darkness. There is a certain romance in darkness and melancholy. There is something mysterious about that which is hidden and unknown. Dark poems may seek to romanticize sadness and depression. Other dark poems are simply poems about sad subjects. The poem "The Raven" by Edgar Allen Poe is an example of a delightfully spooky dark poem. There is much room for creativity in this genre.
Depression has a different quality than the normal range of sadness that you may feel throughout the day. When you are depressed you do not feel like being with anybody. You either sleep way more than usual or you can hardly sleep at all. Similarly, your appetite is either nonexistent or increases dramatically. Your energy level goes way down and you have a feeling of hopelessness about life. As difficult as it may be it is important to get out of the house and get some help. You are not alone.
Addiction can turn a perfectly healthy individual into a complete mess. There are many things that one can become addicted to. The common denominator is that it can ruin your life. Whether it be gambling, drugs, or some other kind of substance abuse, your life can quickly spin out of control if you aren't careful. There are some people that are born with an addictive personality. They may try a drug one time and it can ruin their lives forever. Others experiment with all sorts of lifestyle choices and nothing seems to stick to them. When it comes to addiction, there is nothing fair about it.
