In order to get out of the friend zone with a girl that you really admire, you will need a lot of patience. Try not to take any decisions that are motivated by quick action, as it could ruin your friendship and set you out for the worst.
Over time, females tend to develop feelings for those who care about them the most. Hence, show your care and tell her that you are always there for her. Show her your admiration through actions, and not just by words. Over time, you might break the friend zone and then you will be all good.
