Progressive Muscle Relaxation MP3

An easy to read book which explains how the way we breathe might be contributing to our anxiety.
The author provides examples of how breathing differently (slowly and gently) can lead to profound changes in wellbeing.

A great notebook for paper journalling.
It has numbered pages, index, calendars, and is available in lined, grid, dot or plain. It comes in a variety of colours, hard or soft cover. One of the few papers that resist feathering from gel inks, ink pens and brushwork.
Available online or from Milligram, Dymocks, Paperpoint

The advantage of digital journals is that you can add other things to your pages such as photos, drawings or music. The downside is that many are cloud based. (Privacy)
Handwriting is slower and more contemplative so apps which are good from that point of view are GoodNotes, NoteShelf or Notability.
If you don't like the feel of writing on glass, then Paperlike have screen protectors which help.
