Drawing is very calming and it does actually relieve stress for most people. Drawing also makes you use your imagination which is leading you to a complete whole new world. It really helps you create a creation that could lead to so much more thoughts of your imagination. Imagination is one of the most important things, it helps you unlock that "dimension" to your fictional world inside your head. Unlocking that "dimension" can really express your deep emotional thoughts. It's really important that you try and use your imagionation. No one "has" to draw, just try and use your imagionation to create something others can't.
