Hi Taylor. It seems like you are in the right place to gather information on treatment! You should read the articles that are available on this site and maybe call some of the listed treatment centers. I bet you could also get some help by calling the hotline that is listed in the top right corner of the site.
I know it is really scary ask parents for help. I had to go to through the same thing before I entered treatment. I expected my family to be really angry at me and possible refuse to help me, but the response was very different than what I had expected. They were very happy that I had made a decision to get healthy, and were supportive. Most often the things we fear the most are really nothing to be worried about. Here is a great acronym i have learned in recovery
F.E.A.R.
False
Events
Appearing
Real
I encourage you to talk to your family and I hope that you get the help that you want.
