Is it normal that I'm still stuck on hurt.

You are grieving for a relationship just like you would a person who died. You are quite literally going through withdrawels. Your body was getting high off the way he made you feel, how he smelled, looked, touched, smiled etc.. A very strong neural pattern was burned into your brain. It tells you something is wrong because it's not getting stimulus from the boyfriend. Only time will heal it, thats the hard truth. The good news is that you aren't the only one and that it will pass. One day you will wonder how you could be so crazy for that loser. Try and be greatful that you were in love and had the opportunity to feel what that is like. Many go their entire lives never knowing what its like to be in love.
