I had a lot of other symptoms and was diagnosed with anxiety by a real doctor (not by internet commenters). Plus I had very high scores on inventories that are used to measure anxiety and depression. Also, SPECT and fMRI studies show that people with depression and anxiety have very different brains than people who are mentally healthy, indicating that some people have a baseline level of resilience that's higher than others. And tough love doesn't work. It's just another way to beat up on people who already feel beaten down. I still agree with most of your points, though.
