out of sorts

I've been feeling a little out of sorts today. Not sick, just really tired. I've been thinking too much again. I kind of feel like I've been on one of those rollercoasters like old school Mr. Freeze that goes from 0-60 in three seconds. Or like I'm caught up in a windstorm and my feet can't touch the ground.
Seems like lots of my friends have such good careers, or are in graduate school or have awesome plans for their lives.
I'm moving back to Nacogdoches, and I'm struggling with the same stuff I always do. Who am I really? Someone who wants a simple life, laid back, enjoying friends and relationships, conversations, and family? Or do I want a fast paced life, feeling intelligent, successfull and making lots of money? I feel like I am capable of a fast paced life, and it seems attractive, but am I really drawn to something simpler? Something people here just don't seem to understand?
I am about to get into a teaching program, and will begin teaching middle school english this spring. I am so scared. Scared that ten years will go by and I'll realize that I've lived out none of my dreams. Scared that I will get stuck in one place with no creativity and no ambition, just making money to get by...
I'm still young, I still want to do so many things, and sometimes I just feel so bogged down by, I guess, reality... for lack of a better word. I just feel like I could do so much, but that I'm settling. I want to do something that is my passion, something that I'm good at, but all I really end up doing is hopping from job to dead-end job, finding nothing that will ease my restlessness.
I know I want a few things that Nacogdoches will allow me to have:
1. Spending more time with Shawn
2. Spending more time with family
3. Exploring creative outlets
4. Spending more time with friends
5. Becomming more confident as an adult and with my career
6. Being close to a university
7. being in a more laid-back, simpler environemnt which challenges me to stop and think
8. Being more relaxed

I just pray to God that I will find something that interests and challenges me soon... because right now it all just feels like such a waste. I won't mind living in a small town, as long as I don't have to be there forever and can do something that I love with those that I care about. Please, God, I just don't want to settle.
