请帮我修改下这段英文的语法错误
Dear managers,
Hi ,
Would like tell you face to face ,but a little difficult to say ,so I send a email first then tell you face to face that will make me more courage .
Came to here almost for 1 year ,and learn much knowledge ,even redefine the concept of cashier ,and I know still have more knowledge worth to learn.But so pity i choose to leave because personal reason ,and really appreciate workmate and you,you always trust me and treat me good and help me ,not only at work but also on life.
Have a little period of time to leave from now ,durning the period ,I will do my work well do my best ,and will teach all I know to the person who take my work .you can contact me anytime if you have any question on the job in the future .
Actually I am so hate to part you ,the leaders of inculcation ,and co-works the piece of sincere and friendly ,ok ,best wishes to you
