I used to be overly attatched to my computer when I was first getting to know DF. We don't talk nearly as much or as long as we used to, but that doesn't mean we've become detached from one another. He works 12 hour days at a factory, and I'm at school full time and work part time. We're just super busy and have our separate lives, so the time we do talk is spent catching up. I hated being so attached the computer and that caused a lot of problems in the past--we work much better when we're not constantly in contact, but that's just us. So like others have said, you just need to get yourself back into the swing of keeping yourself entertained, which is often easier said than done! I wonder what I'm going to do with myself when I'm done with school for good next week and have no job lined up, so I'll have little to distract myself with besides hunting for a temporary job.
Try to pick up some new hobbies, or find some friends in your town and ask for their input on what they do in the area and make plans to hang out somewhere outside the house, and get used to detaching yourself from the computer. But if you're ever at home alone and find yourself bored, the internet does offer plenty of entertaining online games, or free streaming videos, or downloadable PC games.
One good thing is that spring is arriving (depending on your area, I guess...I've seen snowstorms and 80 degree weather within the past two weeks here in Ohio
) so you can plan more outdoor activities, which are always good for the spirit
