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:

And finally here is a link to an amazing post that asks multiple people the question "What does home mean to you?"
