To each his own...but by saying that traffic does not allow you to unwind, you're forgetting something very important - WE choose how we react to situations. The situation, such as traffic, does not force us to react a certain way. No one likes traffic, but you can decide not to get keyed up about it. I'm not one of those new age goobers who's into meditation and chai tea, and believe it or not I'm actually trying to be helpful here.
You're holding very tightly onto what appears to be an ineffective and undesirable way of doing things and are trying to force a study schedule into the status quo. You asked for advice and don't like the advice you got, even when it mirrored what you suspected yourself (having to give up the TV). I offered you an alternative, but you won't consider it. If you dig your feet into the sand when challenged with a completely different way of looking at things, you might find your head buried there too. Not you specifically, but in general.
I honestly just wanted to help and offer another way to help you beat the stress of the trip home. I used to live in the city and had to actively find ways to deal with the stress of so many people. I took the bus or train to work and it was better than driving, but I also had to find ways to not get so keyed up with city traffic when I did drive. Music worked for me. Something else might work for you, but at least consider it. Why would you choose to remain stressed about something when there are alternatives?
My last bit of recommendation for you and anyone else on this board - and it comes from an open heart. A few years ago, I read a book called The Four Agreements. It is extremely illuminating and a quick read. It's about the four agreements we make with ourselves about how we deal with ourselves and everyone else. There's a good write-up on it at Amazon and it's probably got a 5-star rating - phenomenal book that shows you how to let go of the way we were raised to think and to embrace ways that free up your thinking so you can see the real possibilities in things and just let go of so much. I recommended this book to a girl in another forum who had some serious self-esteem issues and she wrote me back a few months later to say she bought it and has been much happier since she read it. Pretty awesome.
Again, I'm not an incense-burning granola (I drive a BMW in case there's any doubt there!), but just give it some thought. Sorry to have offended. I just thought you were trying to force a square peg into a round hole rather than trying to change the shape of the hole. Good luck with your studies.
