<human>: for the past six years I've been in a relationship with someone I care about very much and really enjoy spending time with. We share a lot of interests and both have a similar outlook on things. Now, over the course of our relationship she has developed numerous physical and emotional issues that severely limit her ability to function. She can't work, do housework, or shop for amenities without suffering from terrible pain. 

At first I was happy to help, to clean up, to cook, to go shopping for her, take her to appointments, pay bills, but after years of this I feel myself getting more and more worn out by it and I feel like it shouldn't. I'm afraid of talking to her about it because I said I'd take care of her until she got better, but I don't think that'll ever happen, or it'll take years just to see improvement. I feel like a lot of our time together is just me taking care of her, but if I ignore it in favor of doing fun stuff with her then it just means I'll have more to deal with later when I have to inevitably do it. I'm so scared if I say anything she'll be furious with me because she has no way of taking care of herself without my help

more and more I find myself making excuses not to go over to her place because I'm just seeing it as work sometimes... And just thinking like that makes me feel like a total asshole. I just wish she would show signs of improvement. She's seeing people and taking medication, but all it seems to do is keep her in a state of emotional subsistence

Give me the gist of the text in a nutshell
<bot>: I'm feeling caretaker burnout from my SO and find myself making excuses not to go over sometimes. I don't know what to do and I'm scared to say anything
