I honestly don't think it matters when you send the thank you card. I think she will appreciate it at any time of the year because she will know a patient has fully acknowledged what she's done for them.

I also don't think you should spend a large portion of the card talking about prozac and its benefits to you. (I have a feeling you would do this based on your analytically style of writing) Make it more about appreciating her being there...more emotional-related stuff. People love sentimental cards.

Like..talk about how you're doing, but don't make that the focal point.
