Frank, I'm a little confused, are you saying your depression or your wife's depression? Or both?
If you think she's depressed - is she getting treatment? Is she aware of her problem?
Unfortunately if she's not seeking treatment, she'll really need to realise that for herself and seek it... I know how hard it is watching someone you love suffer, because right now I am watching my H spiral with his drinking, but unfortunately we can't make them go get help... It's just something they have to (hopefully) realise for themselves. I hope your wife is getting or does get some treatment.
