Maintain your Finance major. When I was in college, I was in a similar situation and concluded that Financial Planning wasn't for me (the cold-calling component specifically just ended up being a show-stopper for me). Instead, I work in the finance sector, where I've had the good fortune of seeing my salary nearly triple in the eight years since I began. Recruiters contact me weekly via LinkedIn, pointing me to numerous opportunities across the country. If/when I decide to get my MBA, those chances will be multiplied.
College may be challenging, but bear in mind that it is just a small part of your life overall. An extra semester, year, or two years isn't something you'll look back on with regret in ten years.
You should be commended for taking the initiative and seeking advice from others. A finance degree is a fantastic degree to get in general, and it's even better if you can complete the CFP programme at your school in any other way. Financial planning is a specialized area, so avoid pigeonholing yourself.
