I immediately judge someone when they tell me they have anxiety
Why does anxiety come to your mind?
I know so many people with anxiety and they are just weak.
You shouldn't judge people who have anxiety. Anxiety is a disorder that people have no control over.
Not true. Everyone can control their own anxiety.
Anxiety is a disease and people that have it need support to get to the place where they can control it, so your criticisms are misplaced. Try to help and support those people you know with this issue rather than judging them.
