Desperate for help

Hi.

I want to start out with saying that if this truly is a mental disorder, I have not been diagnosed. I have been too scared to live up to that fact that all I do is spit out lies to my peers.

Lying has been natural to me for as long as I can remember. From being a child, wanting to not face trouble and punishment. And because of it, it would get me into more trouble than I had to begin with because I tried to buy my way out of it.

Over the next years out (early middle school and to where I am now, Sophomore in High School), I've gotten better. I've tried my best to convince people of who I am.

Now let me explain that last part. Who I am. I lie about my nationality, when in reality I'm merely some white kid from the midwest of the U.S., as far as I know (I haven't made a huge effort to delve into my past and all of that). I lie about practically everything that is me. I have no interesting life. I'm normal. Average, even. I like to make myself feel as if I stand out by making people think my life is so much better than theirs. But recently, for the first time, I started to t r u l y think that what if I get caught or someone gets hurt or someone finally catches me.

It turned out someone saw past all of my lies and knew that I was nothing but a compulsive liar, they told me. I liked to lie that I knew lots of languages and took trips over the summer. When in reality, I'm scared of the thought of stepping onto and airplane. I did, though, make a huge attempt at learning other languages. Not close to fluency, but I could still make something of some of the words in these languages. I loved to show off my knowledge, though. But after said person saw past everything I saw, I felt empty. I felt numb. I felt like everything I ever knew was wrong and I had not been truly living a average life.

Do you think I am a compulsive liar?
Should I seek some sort of help?

Thanks so much in advance.
