brighteyes, sometimes there are topics that people just do not agree on, and it is therefore best not to continue to talk about these topics with that person. Often it is religion or politics. With you and your cousin, it is the value of medical treatment. Perhaps you can just agree to disagree on this and not bring it up anymore. Enjoy all you do have in common.

How did your cousin discover that you had posted on a blog site for Social Anxiety? If you shared that with her, and then she went and read it--well, perhaps best not to share your whereabouts on the Internet with her.

I agree with talking to someone about depression. I think your family doctor is a good place to start. Good luck.
