A sonnet must have 14 lines and has a specific rhyme scheme of ABAB CDCD EFEF GG. While I can't write the sonnet for you, as that would be cheating, this should make it much easier. Also if you are having trouble rhyming words use a website called RhymeZone. If your teacher is very strict don't use any slant rhymes and each line should be 10 syllables. If your teacher is lenient don't worry about the last two things. I hope this helps.
