I wouldn't read into it too much, your body/mind is adjusting and the ride can be pretty wild for the first few weeks, as emotions fluctuate.
My first few weeks, I stayed in the house, watched TV, played online games and only talked to people at work (out of necessity) and posted on SR.
I felt like if I could have hibernated for a few months, then I would have.
But the feeling passed, as the fresh mornings started to feel really good and my health started to improve, I then wanted to go for walks in the fresh air, go visit relatives and hang out with some mates once again.
Life will open itself up to it's potential once again, given time!!
