Follow your heart and passion! Do what you love and are passionate about! I believe you will be more satisfied if you do what makes you happy. Also, not only will you benefit from it, but others around you will too. If you are not happy in a career, it can affect your overall mood towards yourself and others.. I think your happiness comes first in any decision you make regardless of your doubts and fears. I'm pretty sure you've already made your mind up so go for it! :) Goodluck!
