well you mentioned a step mother.. i have one of those. im in my 30's now, but clearly remember highschool living with that dragon. My step mom was so controlling she timed me getting ready in the mornings (i had 15 mins to get dressed, do hair and makeup--it was agonizing as a teen) i couldnt go to parties or hang out with friends. my brother and i had to get a's and b's or we were grounded (no tv, phone or anything--you came home, ate dinner did your homework, chores and went to bed-and we were grounded forever.. there was one entire school year we were grounded)
my stepmom was a totalitarian dictator banshee so i feel your pain. her and my dad live about 30 mins away, and my husband and i see them a few times a year--she tries to act like my best friend now.
oh and speaking of screwed up families.. my dads sister is married to a mentally disturbed man who was a preacher (he delivers pizza now)--he got fired for showing up to sermon in his pajamas.
for a living i work on an acute, lock down psych ward. i could tell you guys some great stories..
