L.:
I'm truly sorry for the loss of your father.
You have a lot on your plate. Instead of trying to deal with it all at once - break it down to small pieces to make it easier to "digest".
1. The loss of your father - I've not lost mine, but I can see that pain would be horrible!!
2. Work - if you personally cannot change the outcome there, DO NOT stress over this - continue to do the best you can, even when you are hurting, so that YOU can give customers your 100% every time you are in the store.
3. Home finances. If you own your home - see if you can refinance the house to get a lower mortgage. Maybe even get a home equity line of credit to consolidate all the bills at once and be able to "breathe". If you do not - then you need to prioritize your bills - rent first, car payment, then credit cards - call each credit card company and tell them WHAT YOU CAN AFFORD TO PAY. Most will work with you.
4. Daughter's school. I don't know what grade she is in - but our school gives us 2 to 4 weeks notice on things. If you need to bring cookies, stop at the store and buy them if you don't have the time to make them.
Go to your daughter's school or call them and find out their policy on notifications. Let them know that YOU need more than 48 hours notice to put something together. Talk with the principal and let them know you are grieving the loss of your father, adjusting to a new school, etc.
your daughter wants to help?! GREAT!!! Give her tasks to do around the house to allow you to do these other items. If she wants to help with these items, then buy the easy bake cookies - the ones where she can wash her hands and put them on the cookie sheet and bake them. it's OKAY to hand out responsibility. It's OKAY to tell your hubby to do it.
