Pillar of support

Sigh, I felt useless disheartening seeing babyhua cried that day,he cried. All this day, the overwhelming feelings that he held back,the suffocating feelings that he hide well from me finally burst out within one day and all I could do is staying by his side. What can I do to really help him ? I tried my best. I always wanted him to stay strong and I wanted to tell him, " I'll be your pillar of support."
I love you, sth
