Is there a reason your parents don’t want to take you? Are they not serious about their Catholic Faith, or are they not Catholic at all?
If your parents are not actively
opposed to you going to Mass, I would try my best to find some other means of transportation (friends, biking, etc.). But if they
are actively opposed (like they are anti-Catholic, or something), then I would phone your priest and speak to him about the matter (maybe he can talk to your parents for you, or even get you a dispensation). All you can do is make a reasonable attempt to go to Mass. If you do that, and are thwarted for one reason or another, you have not sinned at all. I would recommend watching the Mass on TV or the Internet if you just can’t go.
On a side note, awesome job going back to confession! It’s really great to see you realize your need to have a pure conscience before the Lord
EDIT: I’m praying for you.
