weakness and strength

Last week was very stressful--leaving Philadephia after a month, picking up my kids from my family, and returning to Clemson. This week I got several messages and letters from my family complaining about things I didn't do while I was there picking up my kids. I thought I was doing well to get through it all and get to the airport with all our luggage. Am I strong as I thought I was or weak that I can't do all the other things too? Should I try to defend myself now or is that just getting enmeshed?
