When a child is afraid ,he may shout“请不要丢下我”“请不要离开我”“请不要把我一个人留下” When someone's lover is leaving,the other will say“请不要让我一个人”“请回到我身边吧” “请不要离开我”“请不要丢下我”can be used in most situations. 丢下in Chinese sometimes means abandon

“丢下我”here dosn't mean "throw me away" but"leave me alone".it can express the feeling of loneliness due to someone's going away.also expresses the speaker's wishing that someone could stay.it has a stronger emtion than"别离开我".

请不要离开我 请回来

和我在一起，不要走。 我这算意译吧
