I think my whole life is one big lie
That seems hard to say. Why do you think your life is a lie?
I believe there's a man under the sea who sewed up all my memories.
I understand how you feel, but you shouldn't believe that your whole life is a lie. You should seek help for your fantasies.
What do you mean? I'm not lying about anything, I don't need any help.
I'm just trying to say, that there's a fine line between fantasy and reality. It's not healthy to confuse the two and while it's nice to dream, you wouldn't want to be confusing other people with them!
