My response to this, ironically, was books.
I bought a lot of physical books to read when I get a new job. Life inside the screen is too much for our eyes and mind and we ignore it in the name of profit and capitalism.
If you can, I suggest buy some books, or even an ebook reader if that's not too much money for you, and try to disconnect as frequently as possible.
To be honest, I didn't see results of this yet, but its my bet to stay sane.
Also, maybe some therapy could help you out with this feelings?
