I was diagnosed with anxiety when I was about thirteen. I'm sure I had symptoms of it when I was younger, but my doctors never put a name to it until 2011.

I have trouble with socializing and on a bad day, I suffer through anywhere from five panic attacks to almost ten. In 2014, my mom got a dog from her best friend, Chihuahua mixed with a miniature Yorkie. We had just gotten rid of the dog I grew up, so I guess you could say I wasn't too excited to be replacing her.

Within days of having this puppy, I had fallen in love. I named her Luna after the awkward and qwerky Harry Potter character, Luna Lovegood.

Researchers have been saying for years that dogs sense every emotion humans feel. I can honestly say I did not believe this to begin with. But after having Luna for three years now, I can tell you this is a hundred percent true. When we first got Luna, we lived in a small apartment, and my room was across the hall from my mom's.

At night, when my panic attacks were at their worst, Luna would alert to them. She'd stay right beside me, after going to mom's bedside or barking at my closed door.

Three years later, and Luna is still by my side when she thinks something is wrong. Sometimes, if I'm upset before I go to sleep, or if I have a panic attack, she will jump onto my bed, directly on my chest, with her paws under my chin. When I wake up the next morning, she's still on my bed, under the covers, in the bend of my knee.

Anxiety makes it hard to communicate sometimes, so it makes it easier to have a best friend who can't talk to ask so many question. Luna is everything to me.
