Summarize this article in one sentence.
There are always two realities running parallel to each other at any given time: the one outside your mind and the one within. Sometimes taking a step back is all you need to see that whatever you're concocting in your mind has very little to do with reality. Instead, it's just your fears and anxieties taking hold of you. When you're feeling anxious, remember: is this reality or is this just my made-up reality?  Let's say that your boyfriend texted you back "OK" when you went on this huge, gushing, sentimental streak about how great tomorrow night is going to be on your anniversary. In your head, you start thinking, "Ohmigod. He doesn't care. He doesn't care about me. What am I doing? Is this it? Are we going to break up?" Woah. Back up. Does "OK" mean any of those things? No. That's your imagination running away with you. It may mean he's busy or not in the mood, but it does not mean things are over. People have a tendency of focusing on the negative and seeing the worst in otherwise harmless situations. Trying to focus on what is just in your head will help you  start chipping away at your insecurity, which needs your wild imagination to thrive. Let's say you walk into a party where you know practically no one and you're totally nervous. You're feeling super insecure, you start wondering why you even came, and you're confident everyone is looking at you and can see how insecure you are. False. Sure, they can see you're nervous, but that's it. No one can see your insides. Don't let something totally invisible box you in, keeping you from who you want to be. Most of us get so caught up in the fact that we assume everyone knows how we feel and can tell we're insecure, making the situation even worse. Luckily, this just isn't true. No one is judging you for being insecure because no one can tell. Did you hear about that woman who faked a trip all around the world to even her closest friends and family? Via Facebook, she posted all these photos of how awesome her vacation was, when really she was sitting at home faking it all. In other words, people only let you see what they want you to see – behind those drawn curtains is something much less enviable. Nothing is what it seems, no one is as they seem, and there's no reason to measure your lot up to anyone else's. As Steve Furtick said, "The reason we struggle with insecurity is because we compare our behind-the-scenes with everyone else’s highlight reel." We'll talk about making comparisons in a bit, but just realize that you're looking at everyone's highlight reel, not the actual body of their work. One method of fighting insecurity is just to not acknowledge it. Apart from the fact that this just squashes it until you blow up, it also sends the message to yourself that the way you feel isn't valid or isn't okay. When you're not okay with how you feel, you can't accept yourself. And when you can't accept yourself, you'll be insecure. So take those little feelings and feel 'em. Once you do, they might go away. However, this does not mean to accept your feelings as true. "I'm fat and ugly" is something you should allow yourself to feel, not to believe. Acknowledge that you feel this way and then you can ask yourself why and do something about it.

Summary:
Distinguish between what is real and what is imaginary. Know that your insecurity is invisible. Believe that nothing is what it seems. Listen and accept your feelings.
