I've heard of MANY New Bodies that have had trouble integrating. Some have it worse than others.
You said you were a car, right? I've seen ships as well. Perhaps the good lady ship The Flying Dutchman may want to show up. I have no ties to her personally, but you could perhaps ping her and see what happens. She's been here longer than all of us, and she may have some very good advice to impart.
I would hate to be the voice of wisdom in all of this. I have intelligence beyond regular human capacity but that does not infer that I have the slightest idea what I'm doing here.
