I had to switch schools in the middle of my junior year for smoking the herbals. I feel you man..its tough. Its difficult to go through that change when everything and everyone you know is at that school you go to now. I had to switch school and it was very hard for me to make friends again because everyone at the new school had their set or friends for a long time. Here I was, this new guy. I didn't seem to fit in to any groups. Regardless, I made it through the ordeal. I survived. You will too if it happens. It just sucks to go through it.

As for right now. Try not to think about it too much. Things are going to happen regardless of your worrying about it. You could drive yourself to a panic attack with the worrying. Find something to keep all this off your mind.

When the decision comes just own up to it like a man and keep your chin up and don't worry your parents will certainly forgive you.

Best of luck.
