Sis, I feel your loss!

Dear Sis, although I never experienced such tragic loss in my early childhood as you did, I feel empathy for you, and I feel your pain and suffering. 

Sis, you have done remarkably well. Look how far you have come and how much you have got. You turned out to be a happy, positive, caring, and funny girl despite your rough childhood. I admire you!

I know it is impossible to erase the past, but at least you can try to hold on to what you have now and not to lose them (共勉).
