I think you're going through some positive changes (I would rather use "a-moral" instead of "immoral"). Think of Sartre, who said morality was a tool of the bourgeoisie to control the masses.
It's not unlikely that you'll end up with a new set of ethical standards, one that has been carefully thought over and therefore feels more authentic. But I want to warn you upfront: at first, this process might set you apart from the people you know, if they hold preconceived ideas about morality, and you won't be able to communicate your new understanding. It takes time to find new people who will.
