Too depressed to get married

We've been together a long time, and have been waiting for many years to get married and start a family, but something always wasn't right. Last year, we almost got engaged but we decided not to because we were living so far away from family. We had a great home and a well paying job, but we were thousands of miles away from family. Then we lost our jobs and had to move in with our parents. This year, marriage is completely off the table again, because we don't have a place of our own and can't afford to move out for several years. We also don't want to dip into our savings. I'm also only working part time and going back to university to upgrade my education because we couldn't get high enough paying jobs once we got back etc etc etc. We also have no one to invite to a wedding besides our parents and siblings, because we were living abroad for so long.

I just feel like it's never going to happen.

I've always struggled with depression, so it's hard for me to think long term anyways. Several times in the year, I feel like I'm not going to make it past another birthday, let alone some nebulous distant future when we are married and have kids.

Especially since we're already nearly 35.

It makes it hard for me to want to work on any long term goals or upkeep our relationship, because I feel like what's the point, and am I even worth his time and effort. He's also super anxious about it, and I feel like he might never ask just cause of the nerves thing. It's been drawn out so long that it's kind of a joke between us, and I wish it wasn't.
