Really, she can't react like she normally would. The brain of someone who is depressed shows very little activity compared to someone normal. So basically, her brain cells aren't talking. It's like trying to play basketball with a broken leg. You can put in all the effort in the world, but with that snapped leg, you aren't going to jump.

Do keep doing the things you're doing. It will reinforce in her that she is loved and cared for. Also, consider some help for yourself in some way so you don't get pulled down as well. You can't help her if you're emotional strength is gone.

As far as going out this month, I would suggest still planning on it. Again, getting out and things will help reinforce that there are people there for her that want her around. She won't have any energy because her brain isn't firing on all cylinders, but that's just something you have to keep in mind.

Best of luck!
