Days like this I hate that I work

I've been spoiled this year, reporting to a great manager and being able to work primarily from home.  This has given both me and my kids a huge break of the morning rush and put me in balance with my work and life commitments.

But days like this pulls at my heartstrings of mom-guilt about carrying a full time job with young kids at home.

I had a large meeting downtown, where I was presenting at my department level meeting in a telepresence for 80 people in 8 cities around the world.  It was a really big deal because I'm the only non-manager ever asked to present at the director's meeting on a project I've implemented.  But to attend this meeting, my family, including my parents, had to make a lot of compromises for me...

> The kids had to wake up at 5:30am instead of 7:15 am
> Everyone had to be out the door by 6:00 instead of a the nice range of 7:50 - 8:15
> My parents had to take my eldest for breakfast today then bring him to school.  My mom already committed to my sister with the newborn to help put her classroom away for the summer...so this was an extra task, which they gladly helped with
> Husband had to make sure I was up and also assisted with the kids in the morning.  He helped by actually being the one to dress and brush their teeth while I was busy putting on my makeup
> My mom treated us to picking up the eldest at our doorstep at 6:00, saving me some time to not have to drop him off

So...I did it...I made the 6:47am train, so I'd be downtown in time for the big telepresence.  The meeting went well, I presented without flaw (even though the slideshow stopped right before I started talking...luckily, I printed out a hard copy), and got some good exposure across our team.

But here were the concessions:
> Darling Daughter, after getting changed, teeth brushed, and coat on, went back to her room and sat on her bed.  When I peaked in to give her the 2 minute warning to leave time, she started crying...when I asked what was wrong...she looked at me and said "I'm just still so tired."

> Enjoyable Eldest got sick 4xs in my dad's car outside of school before he even entered.  My poor dad stayed home with him all morning and didn't go to work.  Then my mom, coming home from her work at school, will stay with him until I can get home from the commuter train.  My wonderful father, knowing about my big presentation didn't even let me know until 10:46, which I didn't get until lunch...what a generous sacrifice he made for me.

My heart just breaks...are these accolades at work, almost a pretend show of who I used to be before kids, really worth it?

I know it's just working-mother-guilt that is tugging at my heart since my dad said it was no problem and they have it covered.  But days like this, I really hate that I have this double-life of mom and career woman.

What would I do without my parents?  How in the world do other women who are single moms do it?
