Missy,

Sorry, but I don't sugar coat stuff like others do. I will not say things like
"Awww.. don't worry. You will get over him soon" or "Time heals all wounds & other stuff" I'm something like "Gregory House". I speak the blunt truth.

Right now, you are in the denial state, coz you still think "He is the one" Your emotional part is telling you thisbut not your logical part. If he's the one, he wouldn't have left you in the 1st place. Ever thought of this much? I guarantee you, 10 years later or even as soon as 3-4 years later. You will get over the grieving process. Yes, the emotional scar will be there. But that's just life. You're young, you have the luxury of time. Many of us over 30 years old don't.

People change over time, People's needs & state of mind changes over time. You need to grieve as long as it takes. (Don't take like 5-6 years though, that's waaaay too long) Take my advise, walk up early & go for a morning walk. Get a pet or whatever floats your boat. It will help, it just takes time.
Be well.
