NEED HELP WITH MY SONNET POEM!!?

I have to write a Sonnet poem on being in love with a boy in english, and I'm not really good with poems and was wondering if someone could help me. A sonnet poem consists of 14 lines. The rhyme scheme of it is "ABABCDCDEFEFGG". For example: the last word in line "a" should rhyme with the last word in the second line "a" in the poem. The last word in line "b" should ryme with the last word in the second line "b", etc. And both the last words in lines "g" should ryme with eachother. I would really appreciate if someone could help me, thanx alot :-)
