Welcome to Psych Central Saefyr. I am sorry you feel you are overdoing time on computer but glad you are seeking a more balanced lifestyle.
Why not start by using technology to get away into actual experience.
Trying yoga online, is one way.
Another is qi gong.
Another is to be an active member on Psych Central, reading and responding to posts of people.
There are other ways too. Best thing to do is start with one thing today and build on that.
