I used to feel similarly and used these networks daily, but I stopped logging in after graduating college in 2010 and deleted the accounts a short while after. As a result I started my professional life without these networks.

It is possible to survive without them, and maintain a social life.

>Twitter is used daily for talking to friends

Have you ever considered that this might be a symptom of a problem, not a benefit?

I just finished a month long overseas trip without tweeting or posting about it daily. This gave me the opportunity to catch up with various friends in person to share stories. It also helped me stay present with my overseas friends during the time I was away.

Daily contact is convenient but, barring a subset of lifestyles, not essential.
