I fell like crying in a corner, punch somthing repetitively or just go outside and wait to freeze (yea, that's maby a little bit to mutch tho). My team for the final project at my school just dump me behind my back one day before we give it to the teatcher (that's 20% of my session and i cant afford to let that pass). I do all the recherche for the intervew and they deside to go elswere without me, they probably already give it to the teatcher so i can't do mutch about it. I just, don't know what to do about it and it's way too late now to go intervew someone by myself.

That's not very nice from your team!
You should speak to your teacher. Maybe he (or she?) will agree to give you some delay, or he may give you a replacement work to do. Maybe you can show him some notes you've taken during your research, this way he will see that you did work. Maybe even if you don't have time to interview someone, you still have time to prepare a blank interview, explaining why you want to ask these questions, and show it to him?

yea, for the delay, we already got it for the first intervew. I contact the teatcher, he want to meet our team in this weak. I don't know what's gona happen tho, i am very bad to defend myself and i am alone on my side.
