to be honest,
just keep as busy as possible
surround yourself with friends
pick up some new hobbies.. i.e. read more, pick out new tv series' to watch, cook for yourself more
be more artistic
release some endorphins
don't ruin your life and take the drug/drinking thing too far over a female
as time goes by, you will get over it and move on with your life
in a years time you will forget how shitty you feel right now
in two years time you will probably be settled with a new girl, who fits your personality a lot better
<3 take care of yourself hun :]
go have some rebound sex! you have had the same pussy for 4 years!
time to taste the rainbow ;]
