Capitalize the i's and the beggining of the lines, and use commas when rhyming, but this is a very good poem, and i give it a 5/5!!!
this is how it should look:
I just wanted to thank you
for eveything you do,
for always being there for me
especially when I was feeling blue.
Thank you for making me laugh and for taking away all the bad,
when I was feeling sad.
And for always giing me a smile ,
when I wanted to cry for a mile.
Thank you for worrying about me
I just wanted to thank you for just being you.
