im starting to think im subconsciusly trying to keep hurting myself by reliving the pain of the breakup over and over
I don't think that is the case at all.
im 17 and just finished year 12 and am in the transition into workig life and university and this breakup has really messed with my head of a lot of things. one thing ive found is that i really cant let go, at first i thought it was because i was in love and couldnt just give up
The problem here is that you are 17, you have A LOT of stuff and stress going on in your life right now. On top of all those stresses, your significant other dumped you. It hurts to have someone reject you. As we get older, all of us have had that happen at one time or another, in some way.
What you are feeling and going through is absolutely normal. You are not crazy. But, you are right about something,
this is not you. You are experiencing depression from a break up. As I said, it is normal, and if you give yourself some time, I promise you -- it will pass. Most men do not open up to their friends and talk about a breakup like women do. They have a tendency to bottle things up. Sometimes, that kind of repression builds up too much and the result is what you are stating here. You are fixating on the breakup and you need to stop doing this to yourself.
What are some of the things that you do in your spare time that make you happy? (and don't tell me hanging with the person who just dumped you).

Do you like to play any sports? If there are different sport acitivities you like, get a few of your mates together for a game. Physical activity helps us when we are in a depressed state. It releases certain chemicals that alter our moods in a good way.
Do you like to go to the pub once in a while and hang with your mates? Do you like to go to the movies? Get them together and find a good comedy, something absolutely silly and go see it. Then go out for a bite to eat with your friends.
Think about the things you like to do that make you relax and DO THEM. It may take some time to pass but I promise you, you will start feeling better once you begin to do these things I am suggesting.
Let us know how you doing and progressing. Good Luck!
