A love letter

Dear mom,
This Sunday is Mother’s Day.In order to express my feelings of gratitude,I am writing this letter instead of doing my homework tonight.  ***This is very sweet, but as a mom, also do your homework!***
Because dad works in a distant place, you have to bring me up by yourself in most cases  most of the time.You are strict with me so that you always think you are the stereotypical tiger mother. **** We would usually say "tiger mom." **** As a matter of fact,you are the one who loves me most in the world,and I can’t image what I will be without your guidance.
In my childhood,you looked for the best teacher to teach me play the piano,but I gave up halfway;you tried your best to send me to the city that far from our hometown for the sake of better educational resources,but I played my smart phone, read useless books all day long and got bad scores in the end.I have never known what my success means to you till you told casually casually told me that I was regarded as an unpromising girl by many relatives:naughty,carelessly and always shouting at others impolitely.You still believe that I will be an extraordinary woman,and never show your disappointment.
Sorry,I was too immature to understand the fact that you hope your daughter will have a bright future,just for herself,not for you.*** or you could say "you selflessly hope" instead of "just for herself, not for you."  That's a little more clear and concise.*** What I have done for you?I asked myself,and the answer made me ashamed and uneasy.
Now,facing the crossing roads in my life,I take the one less traveled by.I’m making arduous efforts to realize my dream despite hardship.
I do believe that one day,you will take pride in your daughter and I think it is never too late to say "I love you."

***This is the sweetest thing I've ever seen on iTalki.  I hope your mother has a wonderful Mothers' Day (which we celebrate in the US tomorrow).  She sounds like a wonderful woman. ***
