Coming home to reality?

Some things never change and you fit right back into it like you were never gone. Me and TV are a great example.
But some things have changed and I dont even know the full extent of it yet. They come slowly one by one till you are left wondering what has happened to your life. Creating doubts about what you want from life.
How much can one year change you? Maybe a lot, maybe not at all.
Who am I? the person i was before this year, the person i was during this year or some amalgamation of the two i still have to find. Ask me a few months from now!
