I think you have answered your own questions here. Her lack of acknowledgement is telling you that she is not interested in a relationship with you at this time. So be it. I understand how this can be hurtful when you feel you have done all you can do to open up to her and give her the space to reconcile the problem between the two of you.

Illness or no illness, sometimes we have to just cut our losses and let well enough alone. If you feel in your heart that you have done all you can do to try to repair the relationship and nothing has come of it, then it's time to let it go hon. If writing to her how you feel is what will make you feel better then go for it. Or, just plain writing it out and not even sending it can be helpful too. At least in that way you can get out what you need to say and that can be healing in and of itself.

Your feelings do count. And at some point you just have to draw the line not only with her, but with yourself too and stop beating yourself up over this situation. Letting go and moving on may be just what you need to do hon, for your own heart.

Take good care!
