how are you? plese listen to my worry.

Hello! my name is Nonta,one of TADOKISUTO.
I started TADOKU almost two years ago. I read 180mango.
I write here first time. I am poor at English.
Writing was difficult for me,so I didn't write in English for long years.
But my old student said me she want to write me in English. She want
to practice English.because of going abrord to study about dolphin.

oh,no! I am not good at writing!! Look at these sentence!
please advice me about how to write!
by the way,may I write these things on this bbs?
こんなことをここに書いてもよろしいのでしょうか？
辞書をひきひき、書いてもこんなもんです。
いや、言いたいこと辞書でひいてもぜんぜん出てこないんですねぇ。
例えば、「失礼します」とか「おじゃまします」と言おうと思っても
ぜんぜんでてこないのでした。ふぅ。
　How do you write?　超初心者はどのような手段で始めればよろしいので
しょうか？
