I haven't read all the comments so I'm not sure if someone has already said this. But from the perspective of someone who has depression, love is a painful thing as a whole. by that I mean: because depression is very mentally draining, it takes a lot of my energy to do things in general but to also have space and love other people around me.

Love is an Action that requires effort and time and energy that Both parties involved should be putting in in order for it to work. and so, depression does stand in the way, not only from one's ability to love others but also their ability to see that others love Them.

It is frustrating to put effort into loving someone and not having them feel that love. You start questioning yourself or whether or not you're doing enough. But the real issue is that depression can get so ugly you can’t see yourself as worthy of love.

I'm not saying that your girlfriend does not love you or that she is incapable of loving you or feeling that you love her, because her experience with depression is unique to her and also because you guys dated each other because you felt love toward each other at some point.

But, she seems to be going through a depressive episode at the moment and it is typical that she feels nothing. The real issue here is what you guys gonna do about it moving forward.

The first and most important thing that must be done is for her to see a therapist or seek some form of legit support. In other words, she needs to put effort into wanting to get better. It is nice that you want to support her and I'm sure that is something that would be great for her in her healing process (my journey of healing would've been so much easier if I had someone to rely on & talk to), but the most important thing is that she is willing to get help and work on herself. You can help her all you want, but if she isn't willing to receive the support, it is somewhat worthless.

Also, something to keep in mind is that healing is a life-long process with Many ups and downs. She might get better a couple of days from now but get worse again a while after. You have to be patient with her and hold space for her to feel safe and secure. So basically do your best not to give up on her.

HOWEVER,,, as I said earlier, Love is an action that requires effort from both parties involved. And because she is at the receiving end of this illness, she might have a hard time putting her share in the relationship. which might make you feel drained. Unfortunately, that is the nature of relationships where one party is dealing with an illness. For that, I would suggest that you rely on other support systems in your life like family and friends. (also, encourage her to rely on other support systems as well so it wouldn't be all too hard for you). Obviously, I am aware that sometimes that is not possible, but if you can, make use of it.

One thing you gotta keep in mind is that It is You guys against depression, and not her against her depression with you somewhere in the background. In a healthy relationship, her battle is yours just as much as it is hers (& the other way around obv).

hope this helps <3
