Frustrations

My last couple of days have been awful. Just so very stressful. William was sick last week for a few days and he seems to be trying to make up for it. He has been cranky and clingy and whiny and demanding and confrontational. He is driving me totally up the wall. I just don't know what to do with him. The girls are trying to be good, but half of the time they make him worse. I love my kids but sometimes I wish they would go home with someone else.
I have two tests coming up, and I want to do well on them. I'm stressing over that because I have a friend who has a job and four kids and sings and all and has a 4.0 and just got accepted to a nursing program. And here I am with three kids at home and I can barley maintain a 3.0. I feel really inadequate.
I'm frustrated with all my singing stuff. I really thought that I was doing better and that vocal team auditions would work out differently. Don't get me wrong, I'm happy to be in the ensemble, but I thought I could do better.
I'm frustrated that we had so many technical problems Wednesday at kids worship.
I'm jealous of opportunities that have been presented to my hubby, when I can't seem to get into the program that I want to be in for worship.

I just don't understand why everything is so hard right now. I know it seems silly, but this is my frustration right now. I don't mean to vent to all of you, but sometimes things need to come out.
