What do I do????????????

I am a freshman in college and I just started my second semester. I am taking a combination of business and theatre cles because I want to pursue acting. Lately I have been confused because I know its so unrealistic to want to be an actress, and part of me just wants to give in and major in something "normal" and just forget the acting because it seems so far away and unreachable. Is it even worth the money to major in theatre if you want to be an actress (like a television actress)? I love acting but I don't feel like I fit in with the theatre department because I have never been into clic plays and the theatre atmosphere. But I know this is getting experience, but is it wasting money? Would it be better to just major in business and then do theatre cles outside of school to save money? Also, what else should I be doing if I am planning on acting as my career? Or am I just being ignorant and should I just forget the acting? Please help me!
