My recuireter lied to me and I want to change jobs???

I love the navy it is my dream , but my recuireter lied to me very badly!!! He rushed me to sign the contract at MEPS and take the oath and he chose my job, I don't want this He put me in DEP for 6 mts, I know I can still change my mind and actually completely back out but I don't want to, I want to stay in the navy. I want to start as reserve now first and choose my own job and get my bonus , he did not even include my bonus in the contract , and when I asked him he said he will call me in 2 days and see what he can do??? I am so sad and depressed can I change my contract active to reserve and change my job and get my bonus, other wise i am gonna tell him I am not doing this anymore, Thanks GOD he put in DEP other wise I don't think I would have a choice!!!!
