sucks. my wife was 1 of 3 and she was the blacksheep. her brothers got everything and she had to clean the house behind them. they got cars, etc. she put herself through nursing school on her own dime
Obviously they turned out night and day! shes' awesome
Oddly enough my wife was the blacksheep, too, but at 32 years old she's still looking for approval from everyone and their mother. If you ran over her with your car she'd apologize to you for not leaping out of the crosswalk.
Her mom divorced her dad when she was 2 and then remarried. She lived with her mom, stepfather, and his 3 kids (1 daughter, 2 sons). They were spoiled rotten, and to this day his favoritism still paints the walls. I could go on and on with examples but I'm sure you get the point. For some reason she still bends over backwards for these people and usually sprains both our backs in the process.
But back to your family problems - I'll save mine for another day
