It is souch a strange moodfeeling when you want to cry.

I am not sure how to explain this, but a native speaker would use "feeling" instead of "mood" here.

AtOn Wednesday, I am going to an interview at first time.

If the word begins with a vowel sound (a, e, i, o, u), use "an" instead of "a."

But, i that is not athe reason why I want to cry, although I don't feel very prepare a lotd.

I don't even feel upset, merelyit's just that time is passes so fast, and I want to learn so many things.

"It's just that" is a very common transition phrase in this situation.

In junior coursehigh, I doidn't want to learn anything and, but now I feel how to belike getting educationaled is cool.

I'm not sure what you meant by "junior course", but I'm assuming it has to do with school level.

So, I feel some tension onregret about theis lost, so time, and there is a slight sadness.

It's not wrong, but saying "there is some/slight <happiness>" is a less personal way of expressing emotion. It shifts the attention away from you and ascribes the feeling to a group of people or a situation.

I changed "tension" to "regret" because I think this is a more appropriate word to use for the feeling you're describing.

Today went ait snowfalled - it is so great and unusual to see yellow trees and snowflakes.

You can also say "Today there was snowfall," but most people in everyday speech just say "it snowed" or "there was snow."
