I think I need some "happy medicine"...

I have been out of my "happy medicine" for about a week - week 1/2 and I think I'm going crazy! My kids have been driving me nuts all weekend. Little husband says that it's all in my head - OF COURSE IT IS!!!! It's called chemical imbalance coupled with hormonal imbalance and I'm about to explode! Not to mention that I feel like a freakin' fat cow these days - gonna rejoin WW this week for the 6th (or more) time. Need to make an appointment with the OB/GYN pretty soon too. Birth control ran out this month and don't want any more curtain climbers here. I think I would have to hire a FULL TIME NANNY if I had another one. I have 2 and think I'm going nuts - can't imagine what my MIL went through with 3 boys.
