Im thinking of dropping out aswell..im not going to go into it now.....but to answer your question....
what job can you get in linguistics?

Anthropology
Consulting
Market Research
Neuroscience
Law
Teaching English as a Second Language
University Faculty
Technology Development
Technical Writing
Dialect Coaching

I know some of these arn't specific jobs, but they are areas you could go into...

As for wether you should drop out or not....at the end of the day it's up to you, do you what you think will make you happy...but you wont really ever know what you missed out on....
so wither way you will always look back on your life and ask "what if?"

lol sorry I couldn't be much help...hope you figure this shit out!
