My wife was diagnosed with anxiety about 4 years back and I am starting to really struggle with how to help her.  At first it was very easy to reassure her of things, answer her questions and be supportive but I am having a really hard time over the last couple of months.  I know she isn't attacking me but I can't shake the feeling that she just doesn't trust me because that is the perception it gives off.  She does a great job at telling it has nothing to do with that but it's hard.  She has also done a great job at helping me understand as best she can what anxiety feels like but having never experienced it myself I struggle with understanding why she can't just "turn it off" if she admits she knows it's silly to keep worrying about something or to feel insecure about a situation.  I know it's horrible to say "turn it off" because I genuinely know it's not that simple.  Just because I operate that way certainly doesn't mean everyone else does.  Any advice on how to handle the way her anxiety is effecting me so that I can continue to support her and not start getting frustrated?
