My identical twin sister (we're 22) and I have been roommates for nearly a year. Over the summer and into the winter I suffered with major depression, on a scale that was unfamiliar to me. I ended up leaving my job in the autumn and would spend days/weeks living in my bathrobe barely able to take care of my basic needs (I.e shower, eat...). When my depression worsened my sister took on more house work which I appreciated. She eventually came to me angry about the extra chores she was doing. She would be upset I hadn't thought to do the dishes or take out the garbage out. I explained to her that in my current state I couldn't see how the house was in disarray. 

Very shortly after this first upset, I found, what I thought to be, the best solution. I told her if she left me with a list of chores I would do it. From then on, every time she told me what to do, I would, not fluattering once. I began to feel good about contributing but because of my mental state I still needed her to tell me what she would like done. I felt this system worked well and was proud of myself for keeping up my end of the bargin. 

However, she soon started to become angry/resentful again, she would be upset about having to tell me what to do, she said things along the line of "you are an adult, I shouldn't have to tell you what to do" and "I cant bring myself to ask you to do the chores because of how you are right now". This upset me, I felt she was being unfair, I was doing my best to find a middle ground and her only "task" was to assign me chores. But she wouldn't and then be upset that I hadn't done the chores. 

This conflict was never really resolved, I just eventually got on meds that helped me deal with my depression and I now contribute eveningly, without being asked, to the housework. But this issue resurfaces often in fights between us. She will go off about how much more she had to take on, and how she should have never had to ask me, and that she didnt want to ask me because she saw how much i was suffering. I remind her that I asked her to ask me, and that she cant be mad at me because she decided not to meet me halfway or decided that I was too "fragile" for chores.

I resent that this is still thrown in my face during every argument. I know I was not the ideal roommate, but I tried to compromise and I feel that I shouldn't be held responsible because she decided not to give me chores when I all I asked was for her to tell me what to do. AITA here? Am I not considering her side enough?

TDLR while depressed, my sister took on more housework, I asked to be given tasks so I can contribute, she is upset because I am an adult and shouldn't need her to assign me chores, she still continues throws this in my face even though it is a none issue now.
