Look for a voluntary group. They can be very helpful and often do some teaching. It doesn't matter tht your drawing/painting is not very good, as therapy it helps your concentration. If you feel unable to do atual representation trydesigning something or cartoons.
Hated art at school but thought it might be fun and get some company. Around here its just not provided especially now with cuts. My local MIND had art/writing groups last year but they have gone apart from a group for Ethnic minorities.
