A day in the life.

My day started with my husband kissing me goodbye before the sun was even up, then later on being woken by my 5 year old wanting to talk about the fairies that were (undoubtedly) in her room last night and eating some cereal...in that order.
Both children and I were up, fed, dressed and out the door before 8:30 to start our whirlwind day. First was drop off at Montessori for Kat, then straight over to 3 year old preschool for Drew. After drop off was complete and both children were ensconced in their places of learning I ran up to the coffee shop to meet with another mother about fundraising for the Montessori. I spent 40 precious minutes discussing what to do, how to do it and how to make everyone at the school own it before running home to do some cleaning. I had exactly 63 minutes to myself at home before I needed to run up to get Drew from school.
At Drew's school I ran into a friend and did some chitchat while waiting for the teacher to open the doors. The doors opened, I waited 2 minutes to hear the "what we did at school today" spiel then grabbed Drew to sprint to the car. Once in the car we zipped over the 3 miles to get Kat. Waited in the car line, got her in the car and zipped home to have lunch. After lunch there was about 20 minutes to play before taking Kat to public school for kindergarten and then to speech therapy for Drew. A half hour of speech for Drew, back home again for 35 minutes then it was time to greet the days babysitter and run off to work.
I have two children who attend four different schools. I know that I am doing what's best for them individually but I am unsure of where my needs fit into this picture. We've been running this schedule for 3 weeks now and both children are as happy as clams. Mommy, on the other hand, is not handling it so well. I am tired. I feel constantly rushed but am desperately trying to hide it because I don't want my children to feel like they are living a rushed life. I have dreams about forgetting important things almost every night.
Will this become commonplace to me soon? Will I get used to running like this? Since I know without a doubt I am doing the right things for them, at what point should I stop because it isn't turning out to be the right thing for me?
