Not abusive, just uneven. My mother loved both of her kids (myself and my ISFP sister). My father didn't seem to give much of a crap about either of us -- spending most of his time at the pub or sleeping around with his part-time girlfriend.
I was a jumble of nerves growing up, I got picked on A LOT in school, and could've probably benefitted by some fatherly advice for defending myself, or whatever. Nah, he wasn't interested in helping his kids -- the beer was much more important.
Not that I'm bitter. :P
The kids at school also had their own derisive nickname for me and everything. It was all a lot for me to bear, and it affected every aspect of my life. By the time I hit puberty, I was running on full-on Shadow Power. My fears started to overwhelm me until they became full-blown phobias. I couldn't concentrate at school, so I barely scraped by. It sucked.
