Hi Natasha,
I may be showing my age here, but do you remember the 70's/80's kids TV show "Why Don't You?" and it's opening titles which showed kids kicking their TV and going out and "doing something less boring instead"? When I get the urge to switch on the TV, the theme tune to this show often pops up and I'll read a book, take the dogs out, do some gardening, phone a friend, have a bath....anything else really!
Watching TV becomes a habit and you need something to break the habit. An unusual way to break a habit is to wear an elastic band on your wrist and "ping" it when you start to do the habit e.g. when you reach for the remote control. The pain will remind you that you might be better doing something else instead!
I myself have problems with going out and not having no friends and being overwieght
Here's a motivation for turning off your TV. A study of children found that they burn more energy staring at a blank wall than staring at the TV..... So even if you switched off the TV and remained on the sofa you will be burning more calories!
It's a double win because you burn more calories, and have more time to go out.
Scary as the thought might be, you need to actively boost your social life. What would your TV soap characters do in your situation? Think about what you like doing and see if there is anyone else out there who likes doing it too. Maybe consider doing some volunteer work in your spare time - most of us can find an hour or so a week to put to better use. Although you may not meet life long friends, it will get you out the house and get some attention needs met (which we all have!)
Keep posting Natasha - being on the PC is better than watching TV!
