I liked the poem 5/5 but there are a couple I wouldn't say grammer errors because maybe you meant to do it like that but just somethings that I would change like

You never made me feel concerned and always glad..

I would changed to You keep me smiling when ever Iam sad..
You never made me feel concerned just always smiling and glad..

but thats just me you really don't have to do what I say where all amateurs here, epsecially me lol like I said though i like the poem
