I lost mobile phone

After the last class ,I found I lost my mobile phone.I call it ,closed. At this time ,I was at home.I retarned to the school immediately.I guess I left it in my desk.But when I went there,nothing in it. I suspected the cleaner maybe got my phone.I linked to her. She said she didn't. She told me perhaps she throw it as a rubbish away.A friend and I then find it in every dustheap ,but ……
I am depressed now.
今天好惨，后来翻垃圾的，一袋一袋，倒出来扫，再装回去。打电话给那个打扫的阿姨，她说没看见。因为我今天是最后一节课在那教室上的，后面没人了，所以我觉得可能她拿的可能性较大。但她说没有，可能被同学拿走了
真的好无助，到晚上十点，还是没有找倒。但谢谢杨茜，关键时刻，一直陪着我。
