I'm in my 40s but any general books are fine too.
I'm at the tail end of an extremely stressful period of my life and have seriously neglected my physical health, and mental health to a lesser extent. I do well with books/programmes that tell me exactly what to do and when, as otherwise I have a tendency to push myself far too hard and do far too much (see also: extremely stressful period of my life).
Please share anything that's worked for you or someone you know.
