Making your own choices

People always tell you that you are your own person and you can make decisions for yourself. What I don't understand is when you do make your own decisions or choices your friends and/or family judge what you do. They tell you there opinion and tell you what they think/want you to do. I'm fed up with dealing with everyone else's problems with my life. I'm going to do what I want to with who I want to do it with. End of story.
