I am fed up of being answerable to everyone. First it was my parents, then my in-laws, husband, relatives, boss! I want to wish my life the way I want to without being answerable to anyone. Is that even possible?

You are answerable because you give answers. The day you will stop giving answers you will not be expected to be answerable. So, I think you yourself are putting yourself in such a situation. You are the reason for your own misery. And in a way, because of this reason it is easy also to get out of this situation as you do not need any one else's help to come out of it. You just have to change the way you behave and interacting with people. Just put your foot down and let people deal with it. That is it.
