Giving Stress to God

I'm starting to stress out. And now that I know this: I know how to deal with it. 2 ways: jornaling/blogging, and time with Jesus.
So here's what's going on.
I live with a roommate. She's a wonderful girl, and she's really smart, but she's a little OCD. so whenever I do something wrong, of course she points it out. Now she has great habits and I need to learn how to take responsilibity for where I live, such as not leaving food out and picking up my stuff, but she thinks I know nothing about preparing food and stuff, like she has a specific way she prepares noodles so they don't stick. It makes sense, but I just have so much going on, I don't need her "nagging" at me. And she comes home crabby from work. And I'm sleeping on a hide-a-bed in the living room cuz her apt has 1 bedroom! And I have NO place to put my things! She's moving a to a duplex which has 2 bedrooms, but she's moving in with a roommate, so I'm STILL sleeping on the hide-a-bed. And it will still be a ways from work, so I'll still use a lot of gas. And what bugs me is I say, hey can I turn some music on? No, I'd prefer you not. Seriously??!! So, I'm talking to my pastor to figure out a different/better living situation. There's a lot of people in the church who are willing to help me out, and I'm willing to pay rent. Not much, but a little.
The other things that's stressing me out: my job. I'm an intern at a church jumpstarting a children's ministry. I have less than a week to prepare lesson plans for the summer, plan games and activties, figure out snacks, crafts, and the supplies we need, tell adults what I need from them, and I have no idea how many kids are coming to this thing. That's what I'm worried about!!! It could be any where from 5 to like i don't know, maybe 100? maybe more? That's a WIDE range of possiblities!!! I'm supposed to figure out how to do this job when i have that much on my plate?? And to add more, I have to speak for 30 minutes on what it was like to be a missoinary kid, and I have like a week to prepare for that!!!! Seriously??!!!

Ok God, you know what is worrying me. And your Word says Do not worry about tomorrow for tomorrow will worry about itself. You also said sekk My kingdom and My righteousness first and all these thigns will be added to you as well. So I'm trusting You, God. I surrender. I can't do this without You. PLease Help. In Your Name, Amen.
