This sort of thing varies from person to person. For example, my wife and I are both very introverted and don't really need the human contact part. My wife does work from home full time and loves it. I can do almost 100% of my job remotely and so I work from home one day a week. I could do more work from home, but my coworkers can't do their jobs remotely so I don't want it to be unfair for them. Personally I would recommend against going back to your old job, even if they welcome you back. That won't look good on a resume. Give yourself some time, let your superiors know that this is an adjustment for you and they should be understanding.
