In casual English, we sometimes put thoughts into quotes like this:
I thought, "What am I doing here? I should leave."
The sentences inside of the quotation marks are a representation of your thoughts. You can also turn emotions into a quote like this:
I sometimes feel like, "Why me? What did I do to deserve this?"
You can also ask other people about their feelings:
Don't you sometimes feel like "Whoa, I can't believe I actually live here"?
