It sounds like your daughter is really worried about you.
I would try to play with her for a bit each evening. Have her get out her toys and play something. Before you start to play say "Mommy will play with your for such and such time. Then I have to do some other things and you can play on your own." Reassure her that you will be ok.
Also maybe try inviting a friend of hers over for a few hours of play.
Just reassure her that Mommy is ok.
She loves you an aweful lot or she wouldn't be doing this. So you've done good mom!
Good Luck!
Huggles,
