My Life Is Way Too Dramatic

There is always a time where you're liked by many people like you. You start adapting life in a new place and having nice friends. But things start to get difficult as well, and there is a point in life where there is just so much drama you can take that you breakdown.
So, I am a British girl going to a new school. I have these really nice friends within the first few weeks of school starts. I have a problem. My sister got trapped into a challenge. The challenge was that whoever had the most guests in their wedding was the winner. So now we have to invite over 700 guests. Imagine that. I don't know what I am going to do, but anything is possible.
I am ready. Are you?
