I know what u mean!
IT looks like you only have 16 days to go until your trip and it will be your son's first trip to WDW.
The best advice I can give u is to:
1. Write a list of EVERYTHING you think you have to do in your life,
from buying groceries to ordering a a new washing machine - whatever it is, write it all down.
REASON:

This way you will be able to focus on one thing at a time and all of that stress you have about all these things you have to get to will be channeled in one area- that sheet of paper. You can choose to look at that list once a day or once a week, but this way you are in control and that list is not in control of you.
You can put this list away somewhere and bring it out when you are able to face each task. It's also like imagining all of your troubles inside of a balloon and you watch the balloon fly away.
2. Remember - YOU CANNOT CONTROL WHAT HAPPENS TO YOU -
B U T --- YOU CAN CONTROL HOW YOU REACT TO IT!

Try to remember this when you get frustrated. People get frustrated because they are overwhelmed. What can you do to lessen the load a little bit? Try writing the list.
3. It's your son's first trip to WDW - talk to him about it and I am sure his excitement alone will get you in the mood to go to Disney!
4. What DIDN"T you plan? Let us know and I am sure we can make recommendations for you and help you do some research - such as restaurants, pricing, rides, planning strategies, etc.
5. The last thing I can think of right now - is that YOU AND YOUR FAMILY ARE IMPORTANT - not work, not things, not schedules - these will be wonderful memories you will make to treasure for the rest of your life! How often do you get away on vacation and enjoy yourself? If you're like most of us, it's not that often - so GIVE YOURSELF A BREAK ! YOU DESERVE IT! and allow yourself time to DO NOTHING and RELAX.
6. I recently wrote a list of stuff I had to get done bec. i was stressed as well and it really helped to go thru it and cross stuff off as it got done. Some stuff isn't done but I don't care because not everything can get done! We all want to be PRODUCTIVE every minute, if we're not - we're "wasting time." We have to change our thinking!
7. Get back to us and let us know if u need help planning, etc.!!!
Take Care!!!
