Dear Xiao Xue,
I am really sorry that you lost your wallet.But you are only making more trouble for yourself by not telling your parents the truth.You are getting into debt with your friends,who although will be happy to help for a while,will soon become tired of giving you their money.【高分句型二】(表示遗憾)
Also your studies are being affected as you cannot concentrate.(学习受影响)The only way to solve this problem is to talk to your parents.(和父母谈)Yes, they won't be angry forever.They love you and just want the best for you.
The longer you leave this problem the worse it will become for you.【高分句型二】You have made a mistake,as we all do.But now you must fix it before things become much more serious.(努力解决问题)
