Don’t know what I’m doing with my life

Long story short: I’m in my first year of university (done first semester) and I don’t even know what program I want to be in. I was accepted for neuroscience but decided that I really don’t like chemistry at all. I thought about getting international development BA but there aren’t many jobs and it’s not very promising. I’m just scared because I’ve made my year a mess of all different types of courses and I don’t know what I want to do or what to do. I’m considering environmental science because I miss biology and care about that stuff but 1. I haven’t had the class yet and 2. Someone told me it’s nearly impossible to get a job with that these days since so many people are in it. I’ve considered business but I don’t really have the mindset for it. I’m so lost and have no idea what to do with my life.
