I think I have come to accept because my T has said it so many times. He told me it was OK if grieving took a lot of time, that it was not unusual for it to be drawn out. I think it helps me to accept that it may take a long time if I hear that is natural and normal. I have definitely had those sessions where I got frustrated at being sad STILL. I have felt like, when will this be over?! But I also feel that I have more experience with grief now and am coming to understand it better so I haven't felt that frustration with myself lately. What would help you with acceptance of your grief?
