In a few minutes, this whole thread will be full of different versions of "It gets better, let time heal", but how can they be right? Well...

>she was my life, even after we broke up
I'm sorry, but even if you decided to focus on a special one every day of your life for 20 years, everything you felt, learned and said is still yours and yours alone. Now she's left and it HURTS, so most people's first reaction is to throw away all that experience, because that time has been "wasted", a non-renewable resource spent... but again, this is far from true.

She wasn't your life; but you shared it with her, and now every memory of her feels like fire; but every time you felt joy, love, happiness still remains as yours and yours alone. Treasure those feelings, that's what you've left of her; treasure them as a form of respect towards yourself if nothing else. But those feelings are not a unique result of something special. Options will come, things will change - and they may get either better or worse, but new waters will wash over you nonetheless. Let it cleanse you.
