Don't be sorry. You needed to get it off your chest. Sometimes things just come out, that we regret later but need to be said. I hope you will talk to your doctor about how your meds are working anymore. I am having the same trouble.

I might suggest you be honest with your daughter. Honesty helps her to understand that your moods are not about her and would explain a lot to her. She is a teenager they know when something is not right. The truth is better than their fears.
