Hi,
As for what is the best way to thank her, I think you know best as you know her and know the situation.
But I can tell you from my own experience that if I am not quite sure how to express my gratitude to someone, for example because we don`t really have a close enough relationship to freely express our emotions to one another, I always thank them silently in my mind, in words I would actually say out loud. They always receive that energy, because ultimately whether you say it out loud, write it as a comment online or say it in your mind, it is about sending an energy charge of gratitude - and anyway you do it, if it is sincere, they always get it ![](https://cdn.boardhost.com/emoticons2/smile.png)
