I don't know how to feel about this.

For the past month and a half I've (23M) been going on dates with this woman (24F) and they've been great dates. She's funny, clever and we've been really honest with each other. I think there's real potential here. 

However she has definitely been suffering from depression and I don't know what to do. At times she's advises me to leave, not because she doesn't like me but because she doesn't want to hurt me. I'm trying my best to be there for her and offer her emotional support but especially on her bad days it can feel useless. 

I'm really conflicted. I think she's great and don't want to abandon her during a tough time. Ideally something will change and she'll start feeling better soon but that's very optimistic. 

She refuses to go to a doctor as she says she's tried medicine in the past and it made her feel worse. I'm also slightly afraid that the only reason she's dating me is because she's depressed and I'm there for her and that if she gets better, she'll regret being with me. 

Idk I'm very conflicted about all of this. Any advice?
