Dear ,
I was really sorry to hear of….I wish there were something I could say or do to….
In the next day or so you will receive a little package from me. I hope you like it, and that it will be useful at your present moment. What’s more, please don’t hesitate to contact me if there is anything else I can do now and always.
I do hope you will soon get well again. Be assured of my availability and eagerness to help in any way I can.
Yours sincerely,
