Great suggestion, Anna! I don't know when I started to keep a journal...2 years ago?? And I find it really, really helpful to write my feelings down. It clarifies them in a way that obsessive thinking doesn't. Also, a HUGE plus is that it shows me how temporary even the rawest of feelings are. I can see, almost from a distance, the ebbing and flowing of my life. So if I do have a bad day, I know that that is all it is....only a moment in the grand scheme of things.
Another thought for you gr8, is you might write a "letter to your children" in that journal. It might make you feel better. It's for your eyes only, unless you decide otherwise.
And lastly, congratulations on your 2 months. It certainly is a process, with many lessons and feelings along the way. Be gentle with yourself. Rome was not built in a day, as they say.
