I too am missing good and bad, if it was not for my wife I would never even know, she is my memory now. If I know I need to remember something now I write it down. I know what it is like to miss big chunks of your life. Keeping a journal when you are well enough is a good idea if you can do it. Sometimes I am not up to the journal, I leave notes for myself to read when I feel a bit better. I hope you find some comfort in knowing its not just you.
