We do what we need to do, what pleases us or what we find necessary for our life and protection. If your art is a defense, you need it right now; you work on getting comfortable with the human relationships and cleaning your desk and as you get more comfortable with that, then the need for the art all the time lessens. Symptoms aren't the problem.
Trying to change symptoms never worked for me but I fixed some of my problems in therapy and the symptoms lessened (if they are habits too, after their need has gone away then one can work on changing the habit) or disappeared altogether because they didn't "fit" with what I wanted or needed anymore. Kind of like Carly Simon's,
I haven't got time for the pain
I haven't got room for the pain
I haven't the need for the pain
Your painting is part of you, like dreaming. You can't rip it out of your life, organize it like the desk, "control" it anymore than one can do that with their body, mind, or emotions, as if they are concrete "things". The painting probably knows more about you than you do; ask it to help you instead of treating it like an out of control wild animal.
