I wonder when it will end and when things will get back to normal. I know with me, I have a rule, that I do not take sleep medications, other than to break a bad cycle of sleepless nights. Sometimes, I get so tired that I can't sleep and a pattern begins, that can be hard to break. If I break the cycle, things can normally get back to normal. This is a decision that everyone has to make on their own and have to take resposibility for.
Some people are better off to stay away from sleep medications altogether.
I know, that with me, if I continue to exercise everyday, outside regardless of how tired I am, it is more helpful and I feel better, than just lying around, waiting for the day to pass and thinking obsessively. That's where you can get in trouble. Also, reading comforting books that are supportive like John's are also helpful. They give me the support that I need during a rough period like that. I was reading your posting, and I too, go through periods when I cry and my husband hears about it, but by mid afternoon, I do a little better.
