i was at uni with a girl who did.
at first she was a muslim just as usual, but upon talking to others, having her beliefs challenged - by me and others - having things analysed and flagging up the hypocritical and the irrational stuff etc, she began to question her faith.
we never encouraged or goaded her to do things of course...we respected her beliefs and would ask her to explain...but mostly she couldnt really - she really was exteremly ignorant of 'why' things were the way they were - she just blindly believed - but she would see us out having a laugh and just wanted to do it too.
she eventually began to drink alcohol ...sometimes far too much and eventually she began to change her style - a bit gothy punk.
i left the college and i found out some time later that she had gone wild - and apparently was a bit of a nightmare to hang round with ...just being rude and weird - and basically not the rosina we had known and loved.
not sure what happened other than she was rebelling - (and had seemingly gone too far) - once she recognized that her strict upbringing was not right or the only way, she probably had all kinds of emotions - fear, anger, loss, a feeling of having wasted time, missed out, being sheltered etc
this was 20 years ago (we were 19-20) - i heard about 4 years ago that she was ok now and had not gone back to her religion...
i would like to know what happened at the time though.
actually i felt happy for her, yet guilty...
she had gone through a lifechanging event -because of us - and i was very happy that she was free of the 'shackles' and could move on and lead a normal life - but also guilty that she'd had to do it away from home - more or less alone - because although we were there for her as mates - we didnt really know her that well or really know or understand what she was going through and she hid it well ... though looking back there were a few weird things she did that at the time we just thought 'weird' - but was probably down to her state of mind.
