Is there a career center at you school? If so, you can do some career exploration there possibly. You have tried various majors but haven’t made the connection that it isn’t always the specific major that leads to career satisfaction, there are many variables, and often it has a lot to do with how you think about them. I agree with other posters that you are young and while educated, you lack work experiences to help guide and give you perspective. You haven’t lost your way, you are 19, you just haven’t found it yet, nor should you at your age. Also, life is not a race and it doesn’t always unfold in expected ways no matter how well you try to plan it out. The biggest lesson might be to learn how to enjoy the ride.
