First, relax. Breathe. Now think about yourself for a second. Who are you? You might have lied so much about yourself, but think past that. Think before that if you can, and think about what really happened since then that's changed you. Write it down if you need to. Everyone feels like they need to fit in. Everyone feels like they need to seem cool or better than they are. It's not the easiest thing to do when you either have to come clean or tell them the truth for the first time.

In relationships, there's a lot I can say that you can probably work around with, but my best advice is to try and find who you are first and remember to be comfortable with that. There is NOTHING wrong with saying I don't know! If you really don't know, and it's a delicate subject, make a joke! Lighten the mood! Be yourself and be comfortable with it.

With work and your job interviews, tell the truth. I know this sounds kinda rhetorical... but seriously that's all you can do. Find out what makes you lie. Is it when you are frustrated? Is it when you are scared? Is it to make yourself look better? Once you locate some of the triggers, you might be able to stop them from happening and gain some control.

If you tell a lie, even in an interview, it's best to correct yourself then and there, because that will show them you are trying to be honest, even if you don't want them to hear the full truth. You want to be as honest as you can, so you don't have to correct it later, or feel the need to lie your way out again.

Great Quote: "Don't lie, it means you never have to remember what you've said."
I know it might not have been the most helpful advice, but we're all here with a similar problem. Just stay strong and know there are others out there supporting you!
