First off, welcome to the forums!!! I am glad you found us here!!!!!!!!!!
Finding new people can always be tricky but here are a few ideas. You will be slightly limited since you depend on parents for transportation.
Get into tournaments and meet people that way.
Find the local clubs and see if they have clinics or leagues for players your level.
Just hit the local popular outdoor courts with a bucket of balls and practice serve. If you see someone around your level ask them if they would like to hit sometime.
