Sophie,
I noticed in a previous post you mentioned you are in high school. Susan's has an area that is dedicated to members under 18. If that fits your age, might some of your questions find answers from your age group?
I am not saying you can't post in other sections by any means. I just know that it has been a long time since I was in High school. I can remember some of the experience. However, members here of your age might have or had similar situations.
Not to stop you asking questions but as Dena stated, this is kind of an open ended question with soooo many potential answers that may or may not help you...
With warmth,
Joanna
