I Don't UNDERSTAND PHYSICS! I WANT TO JUST DROP OUT:[?

OMG I DOn't understand it. i'm in 8th grade and i'm taking physics for the first year and i don't have a clue what i'm supposed to do. what is this what is that? I don't understand it. I have a test this coming wednesday and i just want to die. This is way to hard for me an i'm going to talk to my teacher tommorrow. I also have field hockey season so i can't stay after school. the only time i can see her is every other day in study hall cause I have chorus. Like she would give me worksheet and like a little text book and i'm supposed to read it and take notes and underline the important fact. I can read it and it doesn't go in my head therefore i can't take notes. And I've NEVER had this problem before ever like i've never felt this stupid or depressed or confused about a subject ever! I'm a straight A student and now i Know I'm gonna FAIL this TEST!......Any IDEAS? WEBSITES? ANYTHING?
