Hi Francesca and welcome to the forum! It's great that you're trying to get fit and healthy now while you're young and have all those exciting young-adult years to enjoy so much more being healthy (n.b. I said healthy, not waif thin - there's a difference
This time of your life is going to be hard for self consciousness, but you know what, you are obviously one smart chicken to have found this website and asked for some help so I think you're pretty awesome regardless of how "chubby" you are. Try not to let your weight define who you are. If you think of yourself as "the chubby chick' then that's who you'll start becoming rather than "the awesomely smart chick" who happens to be making healthy choices for herself to improve her health.
Good luck with it.
