Open

I find myself usually commenting on the way a poem makes me feel, or how I interpret it, especially a poem shared with such lovely personal and intimate meaning such as yours. I learn more each day by reading and commenting on other poets' work. I find it helps me focus on not only the message of the poem, but the structure and the way it's written. I will say that this particular poem, with such a title as "Open" may benefit from also appearing more open - you may want to pare it down a bit, possibly remove punctuation so that there is no direct break in flow. One huge piece of advice I was given was that a poem is not finished when you can no longer add to it, but when you can no longer remove from it. That is, not overstating by telling, but letting the imagery and language show. For example, the first stanza might be:

Doors. Windows.
Skies open when rain falls
and thunder and lightning strikes.

Your title appears to serve as the lead into the first line, so it may not be necessary to use "open" so often.
But this is very intimate poetry for you as you experience this growth, and I hesitate to offer anything that would sacrifice its true meaning. But truly, reading and studying other poetry is the ultimate way to find your own style and flow. (And to keep writing, of course.)
Thank you,
