Can I just pack up my car and drive away?

depends on the situation and if youre over 18 or not

I went away for a while, but I found away to be no better than where I was. In fact it was much worse, so I came back. I like here better now.

yes.

If you have a place to go and enough food, water, and basic needs, go for it. =)

You obviously have issues. I really have no idea, but then again, this is the vehicle repair category, good choice. I will move it, maybe you will get more answers.
