((((harper))))) it's wonderful that you want to support your wife. i have treatment-resistant chronic major depression (don't worry, there are still options). and my hubby tries to help me, which i am so grateful for. i can be quite negative some days. normally, i'm not a negative person, but depression can make a person into a negative person. cognitive therapy really would be helpful in teaching her how to turn her thoughts around. it helped me tremendously. it has kept me alive, as well. it won't cure depression, but it can keep it from spiralling out of control. i wish you, your daughter, and your wife the best.
