Really stressed out

I’m talking to this girl online and we’re not dating but we’re not jsut friends either. We’ve had thoughts of meeting to get married and to date and all that and she loved the idea she would go in detail about our future house and wedding and everything. Right now she is going through a really bad episode of just issues regarding suicide and other things. Idk id she officially has depression but it seems like she does. Anyway 2 weeks ago she said that she lost romantic feelings for me and she only sees me as a friend which destroyed and confused me because for so so long she would talk about dating stuff(we’ve been talking for a year now) and im wondering if her porbelms are influencing how she feels and i asked her about it last week and she said maybe and now she’s saying no and to “accept being friends” this is really scaring me and hurting me so if anyone can just please help me
