What is Home?

The definition of "home" is absolute in dictionaries but often has a loose interpretation. I tend to take things "as is" but the definition started changing constantly for me.
For example, in high school, home was where I lived with my family.
When I went to college as a freshman, home was the house my parents lived in the city I grew up.
Almost two years ago, I moved to southern West Virginia with my parents. I lived there for 6 months. Home became the state I grew up in and where my friends were, Florida.
After 6 months in southern West Virginia, I moved to Morgantown to continue my degree.
I never traveled much while I lived in Florida. Since moving north, I have yet to stay in one place for longer than 3 months.

When I visit my parents and my old bed feels like a guest bed in a room I barely lived in. A room that has memorabilia of my past thrown about yet still seems foreign.
When I visit my friends in Florida, I'm staying in a cold hotel room.
I live in an apartment while going to school but I know it's just a temporary "home."

So whenever I get asked "where's home?" I'm so confused. I end up saying how my parents live in southern West Virginia but I'm from Florida. I don't really feel like I have a home. For some reason, that seems so depressing. How can someone feel like they have no home anywhere? It's just a lonely statement.

I decided to Google alternative definitions/interpretations of "what is home?"
Here are some of my favorite results after the break:

Signs You Might be in a Bad Relationship

This song is different than the others I've written about because it is in Japanese. I don't know Japanese except a few words and phrases due to my nerd outs on anime, so please don't expect me to translate. I'm pretty much assuming the lyrics are along the lines of what is being portrayed in the MV. That being said, here is my commentary.

I'm not sure if everyone can relate to this video. However, THIS WAS MY LIFE FOR A SEMESTER (4 MONTHS). I'm a person who tends to over-think things after it's all said and done. Especially if I'm constantly reminded of it. I noticed it all comes down to perspective. At the time, all of my friends saw me as the girl in the video- miserable and unattached. I thought I was happy because he met everything on the list of what I thought I wanted. My perspective in the relationship was clouded by my ideals. I didn't realize I was in a bad relationship till it was over....

I was a Slut

I watched Silver Linings Playbook, directed and written by David O. Russell, for the first time yesterday. Honestly, the beginning was a bit slow to me but I became enthralled with the story as it continued. By the way, this isn't a movie review and is more of a reflection.
Jennifer Lawrence's character Tiffany stated these lines that hit home for me.   

I was a slut. There will always be a part of me that is dirty and sloppy, but I like that, just like all the other parts of myself. I can forgive. Can you say the same for yourself, fucker? Can you forgive? Are you capable of that?

No, I haven't lost a husband so I cannot relate in that way. However, when something traumatic happens to someone it affects them in a grand way; either they withdrawal into themselves or cannot get enough of people and intimacy. Neither way is healthier than the other. You could say you'll act one way if something traumatic happens but you don't really know till you're in the situation.
