I Think Alot

I guess it because I'm introvert. I don't know when it started but I just knew that i started getting stuck in my head thinking about so much.
Its great and sad because I think of so much.
I think about the life I had.
I think about the life I want.
I think about all my exes.
I think about all my mistakes.
I think about great stories I want to bring to life.
I think about living to be great.
I think about dying to end the pain.
There is more and who knows what I will think of next.
