what is done cant be undone

From this title ya you know that i still wondering is it the best idea to kick out of school and not to appeal back as i have been asking this question myself, as i worried i cant go back to school in the oct intake i wanted to study is just that i choose the wrong course if i m given a chance i will choose the right course and also study real hard for it and not let my mother down all this time, ya and also another question why i drop out of it, also another one is that if i nv drop out will she patch back with mi but for this is abit no longer there le but the feeling is still there sometimes i listens to music i tend to cry also and at night also i will cry myself to sleep ya, so for nw i have to just look on the bright side of light ya and not look back on the things i have done as it cant be undone. :)
