last few weeks before exam

if they won't allow me to take exam this time too, i'd quit dentistry..i had enough of all that shit..i'm not sure whether my parents would agree or not..but because of some people with power who doesn't even give a shit about the hardship i've gone through..maybe i'm not meant to be a dentist anyway..i'm really really tired..and i don't think i could cope with it anymore if they bar me from taking the examination again..i'm letting go..
