how do you face the age of 18??

Well being only 20 it hasn't been long since I was 18. Senior year can be pretty tough and I even was taking advanced classes so we always had work to do. We even had homework over Spring Break. Some advice I would give to you is don't procrastinate and put things like homework, projects or studying off until the last minute. This is even true for applying to colleges and also scholarships and grants. Putting it all off until the last minutes will most likely just overwhelm you and stress you out more because you feel like you won't get it done in time. Like your exam you have, start studying a little bit each day so when it's closer to exam time you won't be up all night before the exam trying to remember the material. Also what helped me out if taking time out of the day(usually on weekends) to go have some fun. That way maybe for a little while it can take your mind off school related stuff and anything else that might be bothering you. This is a very major part of anyone's life so you're not alone. Keep that in mind because if you feel like you need to talk, do so because most people will understand what you're going through. As for losing friends, I wouldn't stress too much over that because you will make new friends in college. If your high school friends now are truly your friends, they will make the effort to continue the friendship. I know I'm still close to a few of my friends from high school and with sites like Facebook it makes it easy to stay in contact with them if they have moved away.
