This may be the basics, but it's also the FUNDAMENTALS.
This is a really good summary of self care and simple therapeutic tools to manage symptoms of anxiety, depression, stress, grief, & emotional turbulence.
Later chapters on attachment and living within ones own values also provide invaluable information.
It won't cure your problems, but I would endorse this book as a good place to start.
