Oh I'm am so sorry you are going through this.

Two thoughts come to mind.

First, do the two of you do any activities together? Time spent together doing something fun gives her the attentions she seems to need and may help you form a more positive association to time spent with her.

Second, sounds like you could also use some alone time. While I don't know your age or resources, maybe there is some way for you to get out of the house once or twice a week to give yourself a break.

Hope this helps.
