How to deal with parent's expectations on college?

Don't worry, you should do what you believe in. If being a paramedic is what you want, GO FOR IT! & Prove to your parents that you made a good choice. Your almost an adult now. So, if they won't support you, that's too bad. But you gotta stand up & tell them "No, mom, dad, I'm sorry I'm not like my sister---I'm a completely different person and this is what I wanna do with my life, please." Besides, don't parents want their children to be happy? Well, good luck with your career!
