不知道呢，为什么啊？

Social media.

Some people believe that bullshit.

Some people don't feel secure.

Some people are too easily influenced by others.

Some people never experienced any REAL difficulties in life, so they are not able to handle any problems.

The bottom line is that life is too good nowadays, so people have too much time on their hands and some end up worried about bullshit things and become depressed.

主要是，自我期望和显示能达到的差距大，就会抑郁

另外就是peer pressure。别人很努力，也可能会导致这种结果

就是一定要有心态调整！才能减缓抑郁的产生

另外就是最好要结交朋友，或者加入一个supportive的group。有一个supporting system存在，也会降低抑郁的产生
