This poem sounds like an outlet for your emotional baggage. At last, some might say.
Using a simile of being a mother, to being the support to others is a good one. From the pain of giving birth, to wiping noses and other areas. Being that 'rock' for friends and others ogten feels similar, the same areas wiped, the pain felt and what happened to the time of the mother? She watches the family relaxing, but her work continues...unpaid!
Very good and though provoking.
Take care and make sure you carve time out for you!
