I could have written your post myself. In fact, after a day of listening to the kids fighting, I finally just yelled, "I've had enough" and put them to bed at 8:00. Extremely early for my kids. I've found myself yelling and nagging and just griping at the kids all the time lately.
Mentioned it to my pdoc this week and he told me to take my Klonopin or a REGULAR basis. I was rarely taking it, and started me on buspar. I still have to take the latter, it always takes me forever to get up the guts to take a new med. Going to have to though, I've never been a spanker, but lately I've been irritable and snappy with the kids all the time. Guess I should start that med tonight huh.
Good judgement comes from experience and alot of that comes from bad judgement.
