You can possibly help them recover.
But clinical depression is a clinical diagnosis that warrants clinical intervention by a trained clinician. Your role is supportive over the long period of treatment.
You can’t fix it because you are so close to the person suffering. Their state will make you angry, sad, etc. because of that.
And in the end, if the person is not treating their mental illness there is not a lot you can do about it. In that sense, it’s a bit contagious…not clinically of course…but in the sense that the mental health of the people around you can stress you.
Good luck.
Your attitude is good, you care for your partner and are trying to help! You know you're not perfect, and honestly admit your own struggles. Therefore I feel like you'd be the best person to speak into their life, rather than some counsellor.
For me, music helps. Here's a playlist, if punk rock is their style.

Chocolate, words of encouragement ("you're not alone"), and opportunities to talk to total strangers (who will not gossip to friends) have all been helpful to me.
Personally I think the word "depression" is rather vague: does it mean feeling bad? feeling nothing? wanting to die? All of those are different in my opinion, but are often lumped all together as a "problem" to be solved.
Detachment from life can be freeing. I can say "I'll love you to death". The worst that the world can threaten is the death penalty, but I'm not afraid any more (V for Vendetta). This doesn't mean I feel bad! If my life is still useful for serving others (fixing computers, writing code, having the right adaptors) then it's better for us all that I stay here. But I have a greater hope for what's on the other side.
In general Sport helps, there was a study by an Italian Neuropsychologist that showed how 30 minutes of aerobic sport was like a prozac (I'm simplifying, but the concept is this). Do things, action instead of thinking, this helps.
Your partner’s depression sounds clinical, and that's a huge construct, not so easy to grapple, so many variations.
Thus your best bet is to ask your partner what you can do to help.
I get severe depressions. Each episode is days of torture. The word sadness as a description for depression should be banished. Sadness barely charts. All I can do is wait it out. There's nothing anyone can do to help, short of ECT.
Pay attention to small signals of their mood, try to be aware of might be in the future. Sex also helps, although that one might be hard in the moment!
Psychology Today lets you look at nearby professionals and you can filter by specialty and accepted insurance plans. https://www.psychologytoday.com/us
Talkspace is another good option is you're looking for a purely virtual experience but I personally like an independent therapist better.
Another thing you should keep in mind, when someone is suffering from chronic depression, situational changes may not be enough to help them get out of it. There are a variety of causes for depression like this but the root isn't normally something you can get at by making changes in day to day life.
While your partner likely recognizes you are trying to help, they might not want solutions and might appreciate validation of their struggles more. It sounds hard but just being there for someone in their dark moments is hugely impactful.
Make sure to take care of yourself during all of this too. Its a lot to take on but your partner will appreciate your efforts more than you know.
I still go back and reread certain sections when I feel like I'm struggling.
Also, Linus Pauling (the two time Nobel prize winner) has a book "How to Live Longer and Feel Better". Best of luck to you and your partner.
I’d say go to like some super old religious worship (I.e not evangelical American one), like an Orthodox Church one with the smells and bells or something. Maybe like a Muslim service, with lots of chants and what not.
Doing stuff like that after fasting would also make your mind be in a different place where it could have a big effect.
Though if that isn’t someone’s thing it might still be a spiritual experience, but it might be a fearful one?
Psilocybin maybe? Could also have a bad spiritual experience on that but I’ve heard many people say they have a good one. I wouldn’t consider doing that unless you were able to be safe and secure doing it.
I know there are material causes of depression, but it doesn’t change that it is a dark spiritual place. (Like if someone drew a painting of their soul while in that dark place, well it would probably be dark).
I don’t know what material changes happen when people go to a brighter spiritual place, nor always how to get there, but when people do get there; sure enough the material things will have changed (new neural pathways???)
Essentially when people are in that dark place, everything they see is dark. Their friend is getting married, and they wonder why am I not. A friend gets a raise, why didn’t I get a raise.
A good book to read I’d say is “Learned Optimism”
I will speak out against professional help since I know many cases (anecdotal) where such help doesn’t work or reinforces the problem.
My own depression came out of entitlement. I didn’t know I could actually get sadder (which inevitably happened), and it bumped everything back into perspective. It’s a perception issue imho. You think this is as sad as you can get, well let me show you. Guide him/her through the shadow of the valley of death, and let them see the bottom.
Scared straight works.
You know what worked? When he finally gave up.
He stopped catering to her, bringing her food. He started going out with friends and basically ignored her depression. She didn't eat for a day and implied suicide the next. He told her to deal with it, because he wasn't going to any more. Within a day she was up and about.
Sometimes depressed people need a serious reality check to bring them back. Enabling their depression doesn't seem to help long term.
Since seeing this I am also really wary of Professional therapists, after all, it's in their interest for the person to remain depressed.
