Oh how special. What a touching little story you have told us. I think this poem is so honest because we know sometimes that we have to do something, or let go of something and move on, and even though we know this, we struggle to put it into place.
I love the tone of the poem, and how you show us the bond between mother and daughter. Your opening line of a mother's worry and wants for her child, and how you can pick up that she doesn't want you to make the same mistakes that she made with her life, you portrayed this so well with "cracking voice"
I also like how you have a time change scene, from being her tiny little girl, on that swing, a very simple time and memory, and jump forward to now, where it is more complex and life has really started to begin now.
So well put together, and I like the cliff hanger ending because I think it not only fits with the poem, in the sense that you do not know your way forward yet, but it also relates to life, in that sometimes things don't have a concrete ending as of yet, and we have to wait to find out where we end up, or where the story goes.
Brilliant write, I enjoyed this. I think a lot of mother's would love to read this poem, and agree to what you have described.
