gosh there is so many different ways a person can express how they are feeling, work out their problems using different forms of art. I have done and do all of the above.

if you read m any posts here on these forums you will see that many people here express their self in many different ways as part of their therapy process.

how do I decide which one to do, I know what works for me. sometimes thats going into my "studio" (a room in our house set up for all kinds of activities like painting and such) then just do what feels right. sometimes I share my creation with my treatment providers sometimes I dont, what matters is that what I have done was used whats in that room to create something that shows how I feel / felt at that moment.
