Can you help me find a good poem about mothers?

I am trying to make my mum very happy this mother’s day. She is very stressed and lonely and she deserves all that I can give her. I already baked her a beautiful cake and decorated it, but I was thinking writing a huge letter to my mum for Mother’s Day. I want to include a sweet poem that will melt her heart but I am HORRIBLE at poetry. And I mean absolutely horrible. So I would prefer to have a poem by somebody else and write one myself. And I will not use the poem as my own.

Can you please help me? I am desperate!
