((((Paula, Karla and family))))
My thoughts are with you. Being there, seeing someone get sicker and sicker, it's one of the hardest things to do. Yet you are giving your mother a wonderful gift by being there, and she KNOWS you are all there too.
Take care honey, make sure you tell your mum all that you still wanted to tell her, that you love her, and will miss her, but also that you will be fine, and that its okay for her to go.
Kisses.
