请问给父母写一封英语的感恩信怎么写(简单点的)初2的

Dear mom,
This is the first time i write a letter to you in English,so i think i should say thanks to you frist.
That you give life to me,that you bring me to the world.Sometimes i may make you angry,because i don`t adjust my fault.But i am sure i won`t do that things again,i think i have grown up,i must be able to tell the things true or fault.My dear mother ,you are the greatest person in the world,you are the most important person in my life.the love you give me is the greatst one in the world.
My dear mother,i have to stop here,because my vocabulary is very limited ,i will write more letters in the future ,at that time i can write a much longer one to you.
Thank you again ,my dear mother!
Yours son,
XXXXX
