How can art express emotion?

As an artist, art helps express emotions because all of your Words are put into one art piece. People don't quite understand how art and emotions work, because they think art is only drawing. But in actuality, there are various types of art. Drawing, painting, sculpting, crafting and others. Also if you're happy, sad, angry, ect. art lets you use your emotions. for example, if you're angry and sculpting you can crush clay or break the wood and release your physical anger onto your art piece. Or if you're really depressed and you're painting you may tend to either paint light or paint deep meaning the colors will either be light are dark.

The beauty of art is that is can be interpret as many things. While the rest of the world may think it's one thing, you on the other hand knows what it means. And that's okay because it's your art and it's for you only. If others see it, let them think of it all they want. Art has no define nor does it have to make sense, but art can and does express your emotions.
