Great! Look into creative expression therapy or process painting workshops or art therapy in general. For that you would likely need to branch off - on campus there might not be suitable resources - but it is well worth it and group art therapy is not expensive. This may be just what the dr ordered for you and even more important than executive functioning improvement, also you can look into both types of resources in parallel.

I'd say that you suffer from being too cerebral for your own good; any experiential therapy, and especially creative expression and process- (rather than goal-) -oriented activities should be just what you need.

Mindlessly wandering on campus shooting pictures and then posting them online with captions you write yourself is another idea.
