First notebook entry: Introducing myself

小日和  こんにちは　(the kanji would be 今日は, but the kanji version is rarely used.)
環たちの わたしの (私の)　なまえわ　は　アロウツロ　です
綿痴話　わたしは　ニ遊し　（I'm sorry, I wasn't really sure what you were trying to say here）　です
腸痴話　わたしは　メキシコ　から　きましか た


I think you should try to avoid converting the words into kanji for now, and try writing only in hiragana and katakana to get the hang of things first. Avoiding the usage of kanji you are not familiar with might make things a litter easier.
Good luck on your studying! :)
