The hurt of being snubbed by someone who used to be your friend, or being rejected by social groups goes deeper and lasts longer if you’re suffering from untreated depression, according to a study from the University of Michigan. This seems to be adding insult to injury to people who may already be feeling bad about themselves. However, there is a scientific reason to explain this.
The researchers tested stress-reducing chemicals (called opioids) in the brains of depressed and non-depressed people in the context of online dating, where likes and rejections often come in equal measures. In short, when depressed people received rejections they found it harder to regulate their emotions, while non-depressed people were able to cope with the social stress and move on without giving it much more thought. When someone liked them back, both depressed and non-depressed people felt an uplift (which the researchers were surprised about, because depression can affect the ability to feel joy). However, the feeling of social acceptance was short-lived in people with depression.
