The first thought I had when I read this poem, is that I loved the metaphors you used here. You seem to set up the poem as your friends and family as being fine china and in turn that tells me they are the most precious things in the world to you. After reading the second stanza, I think the two key phrases within the poem itself are fine china and 30 years. Within that it tells me that this person you are referring to are your children or one of your children in general. You have been a parent for 30 years perhaps? There is never enough superglue to fix the problems this world has and I love that you used this. People always think of super glue as an end all be all of fix it, but this problem could be on the inside. I really love the ending sentence because it stands out well on its own, and in the end I think that is the crux of the poem itself, You have tried to help for so long that you have become tired yourself and you don't know how to heal yourself like you heal others.
There is nothing I would change punctuation or grammar wise, from my perspective everything is well written.
