I'd start by looking for a youth development program in your area, lots of places without but the NE has a good number of them and some might be nearby. As for joining a local club ride I can't say. Finding them will be easy, just google cycling clubs in the area you're in and once you've got names check the club's facebook/insta/webpage or whatever they have, they'll often list group rides. You may find that they have slips that they want signed off on by a parent but I wouldn't be surprised if they didn't require a parent present at least for the first few rides while they determine if you're even safe to ride with.
