Kate Middleton gave the world an update on her journey with cancer and when the public will see her next in a deeply personal message released on Friday.

I have been blown away by all the kind messages of support and encouragement over the last couple of months, the Princess of Wales wrote in a message shared with HuffPost.

It really has made the world of difference to William and me and has helped us both through some of the harder times, she said. I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days. On those bad days you feel weak, tired and you have to give in to your body resting.

But on the good days, when you feel stronger, you want to make the most of feeling well. My treatment is ongoing and will be for a few more months, she explained. On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home.
