Leave me alone!

I just told this to my son. See my lovely daughter in my arms there. That's what she wants to do all the time. Honestly, most days I'm not bothered by it because we are driving around and I get some space from the kiddos. But today, we were home all day long, and therefore she was on me most of the day. Also, my son did not take a nap, so I am so drained from giving attention all day, no break. I feel guilty for wanting time to myself. But I know I need it. As soon as I got my daughter out of my arms and into the swing, my son wants to climb into my lap. These little blessings can be suffocating sometimes. I love my children dearly-of course you know that. Days like today just leave me feeling like I want to tie on my running shoes and take a long, long run. What I would love to do is wake up early enough to grab a shower, have some prayer time and read some of God's word. What a great way to start the day! I just have zero discipline right now, and I'm tired ALL THE TIME!!! What is a momma to do? Where can I squeeze in some time to myself? I know I will be a better mommy for it!
