Please correct my son's diary.

My son wrote a short diary today. I think several things need to be corrected. But unfortuately I am not sure what they do exactly. Please read below and help us. Thank you.

I have not only to rewrite my essay, but also I need to review the lesson. I now see why people are addicted to drugs because it's like me with games. I regret wasting all the money I spent on games. A drug addict can become clean but I can't. I will not be clean because I have placed a heavy burden on me. Not only I have to write one essay a day but also I need to reveiw vocabulary! I wish I could go back in time and tell my self "Daniel, no matter how low the cost, don't buy anything without dads permission." Not only I cannot get any games on my Ipad but also I can't play games on week days!
