短文改错

Hi, Janice，

It's been a month since I came to this new school and I really want share with you some of the problems I have been experiencing.

As I tell you last time, I made three new friend here. We hang out together during lunch and after school. We’ve been spending a lot of time sing in karaoke bars. It’s been three Saturdays now and it really costs me many. And I started to see this as a time­wasting activity! In fact，I don't like to go anymore, so I'm afraid I'll lose their friendship. How do you think I should do? If you are me，would you talk to him?

Please help with me and give me some advice.

Grace
