Whilst she isn't to my knowledge dead, or come to harm, I know what its like to lose a loved one. I still see my ex fiancee's cute, round face and infectious grin and hear her bubbly, lively, vivaceous voice in my head all the time. I haven't seen her in maybe 12 years or so and miss her like I'd miss an arm if I lost one tomorrow.
People say things like that get better with time, etc. etc.
They don't always, and I am as sure as I can be that this girl, is someone I won't ever 'just get over'. Other people I have before but she was special in every way.
