I use antidepressants to help me maintain some pain control, helps with my mood as well, but I smoke weed, and the combination works out great. A lot of people honestly can't help feeling depressed, it's chemical changes in their brain that are beyond their control, and the only way to make them feel as normal as possible could be medication... So don't judge it until it's happened to you.

Have you tried talking to both her and her hubby about this?
