There’s a new survey out that says Facebook and Twitter can increase anxiety and reduce confidence. Have you noticed a difference in your moods or behaviors?

The survey shows that more than half of Twitter and Facebook users believe their behaviors have changed. Of those who are different, 51-percent say it was a negative change.

Most respondents say that after updating a tweet or status, their confidence plummets. Results also indicate that people are comparing their achievements to to other Facebook/Twitter users.

And this obsession with social media is keeping people awake at night. About two-thirds of those polled say it’s hard for them to relax or sleep, after looking at their websites.

If they are in a position where Facebook isn’t accessible, 55-percent say they feel very uneasy. Meanwhile, some people who try to escape the online pressure claim to feel increased amounts of anxiety and “cold turkey” symptoms if they turn off their gadgets.
