I need help analyzing *"Sing No Sad Songs" by Christina Rossetti. Please help!

When I am dead, my dearest,
Sing no sad songs for me;
Plant thou no roses at my head,
Nor shady cypress tree;
Be the green grass above me
With showers and dewdrops wet;
And if thou wilt, remember
And if thou wilt, forget.

I shall not see the shadows,
I shall not feel the rain;
I shall not hear the nightingale
Sing on as if in pain;
And dreaming through the twilight
That doth not rise or set,
Haply I may remember
And haply may forget.


*Also known by the titles: “Song” and “When I Am Dead, My Dearest”.

Let's see- I think she's telling her loved one to live on when she dies, because she can't be thought of with them anymore. Just keep living life, and move on from what happened.

a wonderful song... no asking for "remember me", lighthearted, feeling as a part of nature, drifting softly away. Yet its not as simple as that. Sort of sadness about NOT FEElING, HEARING, SEEING whats going on in nature makes this song subtle. even the dark moments of life (shadow, rain, painful songs) sound like bloodful remembrance of the beloved existance on earth. That is the unique balance between been forgotten and being alive.
Sorry, my english is a bit rosty, I hope it doesn`t really matter.
