Does anyone else get this? and is there a name for it?

It sounds like you are a bit of a loner and also restless. Not everybody likes to stay in the same place with the same people for long. In my case I put it down to no siblings and no kids. That's a situation I really love but like you I tend to want to get back home after a while and can't stay put anywhere for very long. I don't need people around me and I like to be in charge of my own moves. That's all.
