<human>: Can you condense the text into a few key points?

I've been dating someone on and off for a while now who has depression and recently ADHD. It's been rough, I'm sure I don't need to elaborate here, but when things are going well they go really well. We share core values, ambitions, we're both attracted to each other, and I've never met anyone like her. The problem is that after 2+ years, she still can't say she loves me. Her reasoning is that her depression is making it impossible, and that she needs time to work on herself and to be comfortable not relying on others (after being in a long term relationship right before she met me where she was never alone and might have used it as a crutch). Part of it sounds like what someone would say if they just don't think the other person is "the right one", but I do believe her when she says she just needs time to get herself together.

My question to Reddit is how to proceed. After seeing her recently and having a fight, she reiterated how she needs time and space and I agreed, I have no plans to talk to her for a while and will let her initiate from now on. I know you can't put a timeline on something like getting better control of your depression, but if anyone else has ever been in this situation, did the person ever come around? Have I essentially lost her for good?

She means the world to me, and being extremely busy in my job (new medical resident), I have no plans to date around or be with anyone else, I have little enough time and I've always been comfortable being by myself and out of a relationship. I know I can't wait forever, but I need to believe there's still a chance for us. Any advice would be helpful.
