what is the best response 2 "mommy y r u crying?"

[cat03]

You shouldn't beat yourself up, sometimes I had no time or place to talk to a friend over the phone and ended up crying in front onf kids 2 or 3 times. But it is best to wait 'til they are sleep for you to have a good cry. You are their constant pillar right now, their safey net, and seeing you cry often might not be the best for them. I do understand that you had a breakdown and it happens, hope you are feeling better today.
Don't mention the fact that they might stay w/their dad unless that is written in stone, they might thing you dont' want them or something.
