Well, here's an odd one. This place stopped feeling like "home" to me quite awhile ago.
For awhile, it was kind of a lifeline to me since I had no social outlet whatsoever and little support for changes I needed to make in my life. I loved this place and dedicated a lot of my energy and focus and affection to it. But eventually things changed. While I lamented the change, I couldn't eventually deny it and redirecting myself elsewhere in life.
I guess people eventually change, and groups change, and situations change; and you enjoy something for as long as it lasts, and then when it naturally starts to end, you let it go versus trying too hard to keep it on life support. If we're fortunate, we find some people who change in similar ways as we do and so we all can stay together to some degree; but sometimes things just ebb and one can't live in the past.
