Hmm what can I say? its normal to be tired in the morning …what ever you choose try to see 10 years a head and will you be happy with your choice then. I started work at your age and tried to get back to school(cause the I work I had demanded it..) at the age of 23 witch didnt work out cause i became interested in politics and became an activist 24/7( I did a homer simpson…see there is dog running!), I havent regret it one second, but when you are into going at school and know you want a good education, I think it will be easier to go on studying for while then take some years off and sort out where to go what to do…but whom I am to say this cause I didnt do it, so take it as friendly advise.
