How do you know?

I thought I knew what I wanted to do with my life. I committed myself to a certain major that I am currently doubting. How can you go from being so determined to go in one direction to slowly drifting off into the unknown?

For three years now, I have worked hard to getting to where I am at now. I convinced myself that I wanted to be a doctor and that I wanted to major in biopsychology. I improved my grades and transfered to a UC and now I am freaking myself out that it's not right. Was I going this way for the wrong reasons? Was I ever really that into being a science major?

I have always been told that I am a good writer. I always brushed that off which is another reason I never considered to major in literature. I like writing. I know I'm good at it and it has also been my therapy. I'm a creative, visual person and I've let that go. I've ignored it and pushed it out of my life. I'm just stuck in a rut right now and I don't know what exactly is the right decision for me. I don't know what to do with my life. If I ultimately decide to be a lit major I'd need to transfer out of this university... yet again pushing my life back. But what if I get there and decide I made a mistake?

This seems so juvenile. There are so many other dire problems out there... I just don't like being confused and lost in life. I've always known I wanted to go in certain directions... now I'm not so sure.
