An scene i have seen way too much in real life, the illness of one family member creatingphysical and psychological diseases for it's caretakers. While it's importante to care for our loved ones you also need to take care of yourself and not diminish your own suferring or you'll end hurt too, unable to help. If it weights too heavly seek help in your family and community or at least people that can listen and not judge.
I hope Wiaoyu doesn't try to hide those fellings and frustrations from Mu Ye help now.
Thanks for the translations!
