Lonely days 寂寞的日子

I am very lonely in the hospital, there is since I am the only one one in a three patient in the triple ward. I am unable to leave the bed as there is a fracture in one of my lumbar vertebrae lumber. Eight hours of watching TV, or reading with one hand (because my other hand need to be used in is connected to the IV. intravenous infusion), is my all life. [Clearer to say, "My daily life consists of eight hours of watching TV...."] I am looking forward to returning being home soon earlier.

Take care!

在医院里的时间很寂寞，三个人的病房只有我一个病号。我不能下床走动，因为我的腰椎有骨折。八小时地看电视或者用一只手看书是我一整天全部的生活。（我的另一只手因为输液不能动）我盼望着快点回家。
