I have a close friend who is basically crippled from her anxiety. She used to be like a free spirit, happy, bubbly, almost child-like. Then she had an episode, and got diagnosed with a disorder. She started taking medication, and she's no longer herself. Everything worries her. For the first month or two she would be in tears twice a week, worried that she'd say the wrong thing, or already had, or will in the future. Anything she loved was a source of anxiety for her. She's been doing betterish now, but she's at school and finds it really hard to focus and get stuff done, which makes her even more stressed and less able to focus.
When someone is chronically worried and anxious, how does one help? What can I say, other than boring, stereotypical platitudes? How can I make sure I'm a meaningful source of support in her life?
