Overcoming dependancy on superficial comforts?

I am in a relationship with a wonderful, brilliant, gorgeous man. As this is the first serious relationship I've ever been in, it's also the first time I've realized how much I depend on superficial things for comfort. It started with trying to break a habit of comfort eating, which was quickly followed by a new habit of playing video games or reading the news online for long stretches of time- to the detriment of my relationship. I've broken this last habit, too, but now I feel like I'm grasping about for other casual escapes from my daily life. I have a wonderful job. I don't make a lot of money, but it is something I believe in and enjoy doing. And I could not have imagined a better partner or love than the one I have now. I know I was sort of raised in this way- to be comforted by television and food- not deliberately, but just out of the immediate necessities of providing for a family of four on low pay. I love and respect my parents, but I want out of this mindset.
