Relized something

I have realized that nothing last forever. Including friends. We all have to move on. And after 10 years later you might not even remember that person. it really scares me, but thats reality. At sec 1 you miss your primary school, at JC/POLY 1 you miss your secondary school. im really afraid to move on... i wish everything will stay the same. well, nothing last forever. Im at the point of deciding whether to go back to sg anot. will i be able to fit back into the education system? and fail all my subjects? or will i stay here and go back to sg after university? im scared to face reality. I HATE MY LIFE. i really dunno what to choose...
