I think for a lot of women in their late teens and early twenties, the occasional 'identity crisis' is normal. At this age, it's expected for you to experiment and try new things, new looks, new lifestyles all while having an idea in mind of who you want to be. We often try to attain these ideals through our experiments, but are left feeling more confused than before.
We're always told by the media what looks good and what doesn't, what beauty is and what the current trends are so understandably it's a difficult decision when it comes to deciding what we really want to be like.
