@petrichor Maybe the pictures you painted while in rage are simply that ... and definitely not the whole of you.  Rage has many aspects .... but we do not want to cling to it .... but let it go ... I have felt a lot of rage too ... and was encouraged to express it, but I do not paint or draw ... I express it through walking fast or digging in the garden, or through some dancing ....Often I do not even realise til later ...

Rage in itself is simply a response, and it eventually subsides ... a good thing about it is ENERGY ... and maybe even the ability to defend oneself later, long after the time in childhood when we did not know how to defend or selves or have others to do that for us.  

The important thing after expressing rage is to be able to calm down ... and I hope you have some ways to do that ....
