I am my mother

I lay worried through the night
Always willing it to rain
Her demons are mine to fight

I am my father
I never say when I'm in pain
How could I know what you contain
We're so stuck in our ways

I am my sister
Nine times out of ten I get it wrong
By her side I do belong
We're bound, never to part

I am my brother
Hide away for me to find
Not an idle bone in that mind of yours
Mystery to me

I am my lover
I weigh half when he is gone
Need him more than I let on

We're all caught up inside
I weigh half when he is gone
