What it is
Not a self-help book.
Nothing here promises to fix you, and nothing here has a timeline. Grief is not a problem to be solved and this is not a programme to complete. It is a handbook: a set of things worth knowing, written plainly, that you can open at whichever page matches the day you are having.
Loss is not only death. A relationship that ended. A country you left. A body that used to work differently. A future you had already furnished in your head. If it was real and it is gone, this applies to you.
It covers the body as well as the feelings. The exhaustion, the weight on the chest, the grief brain that loses words and keys — and what to actually do about sleep, eating and seeing your GP while you are in it.
There is a part for the people supporting someone. What helps, what does not, what to say, and how long to keep showing up. You can read that part on its own.
