It's usually a good idea to be discrete about your developing abilities and magical interests at least until you are surrounded by mosly supportive people (your adult years) or until you cannot be physically or emotionally harmed by unsupportive people (and there will always be unsupportive people regardless of your age).
People can usually only tease and abuse you with information YOU have shared with them. I'd keep quiet until you're a little older and in a better place.
It's not that you have anything to be ashamed of - quite the contrary, these skills are gifts - but you have plenty of years to be "out of the broom closet" and to surround yourself with higher quality people. Many Neo-Pagans start their year and a day training with a vow of silence, at least for that time period, which prevents newbies from over-sharing in this exciting "discovery" time.
