I don't think that you should be afraid of your parents. I know it's a hard task to gain the confidence to tell them that you are an adult and that you choose to help yourself. I really dont' think that they will have a problem with you helping yourself and if they do go find a therapist on your own and tell them your situation. They may help you to get out on your own and on your own two feet. Not only that they could probably work with you on the paying part. Some states offer free services so look around and see what you can find!! Good luck!!
