I don't think that you are depressed I think you are normal. I think that occationally all of us feel this way. It is normal to lust over things we do not have. What about getting a slightly unhealthy snack, going to the library checking out a dvd, and watching it on your computer. I have done this a few times and each time it sends me right back into reality. Meaning that A- I don't have time for this, B- I really don't enjoy this, and C- there are many other things that I would love to be doing.
Good luck! I have been t.v. free for almost 5 years. It's wonderful!!!!!!!!!!
