如果我真的很爱你。。。 If I truly love you that much…

如果我真的很爱你,那我一定。。。
If I truly love you so much, then I would surely…

时刻想亲近你,分分秒秒都不分离。。。
want to be near you every moment, and not to be apart for one second…

对什么也提不起劲。。。如果见不到你。。。
lose motivation to do everything… if I cannot see you…

听到你的声音就高兴,对其他的事马上失去兴趣。。。
be excited to just hear your voice and  lose interest in all other things immediately…

收到你的信就欢喜,反反复复读每一行、每一句。。。
be thrilled to receive your letter, repeatedly reading every sentence and every word…

闭上眼睛,满脑子想的都是你。。。
close my eyes and my mind full of thoughts of you…

觉得世界再怎么美丽也比不上你。。。
feel no matter how beautiful the world is, it cannot compare with you…

很多人都说我很爱你,但是主啊,有谁知道我常常问自己,我到底是不是真的那么爱你。。。
Many people say I love you very much, but O Lord, does anyone know how often I ask myself whether I do truly love You that much…
