Feel blue 表示感到难过或情绪低落，通常描述较轻的低落心情，例如因天气、假期结束或思念朋友而不开心。它是非正式表达，适合交谈和 IELTS Speaking；作文里 feel sad 或 feel unhappy 更中性。

feel + (a bit/a little) blue; make someone feel blue
- I always feel a bit blue on Sunday evenings before a busy week at work.
- Rainy November weather makes a lot of people feel blue.
- She was feeling blue after her exchange year ended, so her friends took her out for dinner.
修改原因
修改前Since my best friend moved abroad, I've been feeling myself blue.
修改后Since my best friend moved abroad, I've been feeling blue.
Feel 描述情绪或身体感受时，后面直接接形容词，不需要反身代词：I feel tired、I feel blue。因此原句只需删掉 myself。
Feel blue 常描述一时的低落心情。Depressed 可以表达更深的消沉，具体程度要结合语境：After months without work, he became depressed and stopped going out。另一个带名词的说法是 I always get the blues in January。

blue — 假期结束、下雨、又回到办公桌前，这个情境表达的是心情低落，所以选 blue。形容人时，green 可以表示脸色像要恶心呕吐；表示嫉妒则通常说 green with envy，都不符合这里的意思。
