My kids were 15 and 17 when I got sick and were witness to most of my behavior. I was very open with them when I was first dxed depressed then dxed bipolar. They didnt really want to hear it, moms arent supposed to get sick, plus it was scary. Usually they would say stuff like 'just stop being sad.' As they got older it wasnt as big a deal, I have only had one major episode since that first one with them still home that involved my first and only, so far, trip to the hospital. It doesnt usually come up anymore but when it does we are matter of fact about it. They are 22 and 24 now.
