An exhibition by Barbara Van Arnam is always noteworthy. The artist’s “Better than Prozac,” featuring work in drawings, paintings and sculpture, focuses on a world of “infinite positives” in the life around us that can provide support and tranquility in the face of societal anxiety. The opening reception is part of monthly ArtHop, the open house of studios and galleries in the downtown and Tower District neighborhoods. Van Arnam’s show runs through March 29.
