Is it normal to get anxiety?

I just put in my application to college to study abroad. so many people are telling me I have a good chance of getting it. the thing is I want to go but I also don't. I've express to my parents this feeling, and they've basically said (because the program is either 2 years or 4 years) that if I really try my best for the first year and don't like it they will take me out. It's a reasonable deal, but I'm scared. I don't know what I want to do yet career-wise, but I know this college will be good to get my starting degree that can be used for anything. I'm really scared because I have no idea what I want to do for my career, so I feel like I'm lost and won't have a job and will be incomelss. but also what if i choose the wrong career and am unhappy? but I'm also scared to move to another country and turns out I don't like it, and I have to stay there for at least another year. I'm also scared i won't like the change and will be homesick and i still don't know who i am. like some days i think i do, and others i don't, and they allow dating at this college and I'm scared i will have a crap personality and won't fit in, or no one will want to be my friend. I'm scared that i will be pushed into forcing myself to like it, and i wake up each night getting anxiety over this. my parents have said they'll come to visit during breaks but is this normal? has anyone else gone through this?
