Experts say that comparing yourself with others on Facebook can lead to feelings of depression. Researchers examined studies from 14 countries that included 35,000 participants and found that Facebook users were more at risk for depression when they felt envy, accepted former romantic partners as Facebook friends, made negative social comparisons, and made frequent negative status updates. They also found that gender and personality influenced the risk, with women and people with neurotic personalities more likely to become depressed. However, researchers stressed that online activity can also help people with depression who use it as a mental health resource.
