It's hard to believe that one could hide a mental health disorder for long. I have had relationships with two girls with anxiety and its effects are easy to see. One had a nervous breakdown driving on the highway, eventually beginning SSRIs after the relationship ended, and the other needed to take medication daily to function normally. The second had started taking meds only briefly before we began dating and so it was a constant battle(? not really the right word) for her to discover that she could do things while on the medication that she was previously too afraid to do before, such as socializing in large groups and other things like that.
