Freaked Out

OK...I am sitting here at my desk hoping that the fear is going to subside soon. I don't think that it is. I am so afraid that I am not ready to student teach or teach my own class. Do I know enough, can I be effective, will the kids like me or respect me? I am just so confused and not knowing where to go.
We have to do a online portfolio. This is the craziest thing in the whole world. We have been given this program and somewhat explained how to use it. So I am doing all that I can and continue to ask questions to the teachers who are supposed to be there to help and they can't or won't. I am not so sure anymore. I guess you could say I am frustrated and just a little depressed. So all that said I would appreciate any prayers you could send up for me.
Thank you for everything in advance and just know that I am maybe a little crazy but eventually it will all calm down.
Thanks for reading
