After coming home from work, I don't want to do anything but lie down and play with my mobile phone. How to change it?

This is a typical internet infatuation. If you go on like this, you will be divorced from reality. It's not depression. You must give up your dependence on the internet as soon as possible, make more friends, participate in social contacts, get in touch with the society and exercise more, and try to keep yourself busy.

It must be implemented immediately, and it can't wait any longer.
