Sounds like an amazing person. The world was better for having her here, even if it was cut short. Sorry for your loss. Really, no one can replace her, but she does live on in everyone who knew her.
Like my bro. He wasn't perfect. He was kind of a wreck, but he had a major impact on a lot of people for good in his short life. Saved them from bad situations, overdoses, etc. I don't know what this means psychologically, but I had a dream within a year after he died. I was in the same house where I was sleeping at the time of the dream, it was day time, I was standing and looking over the railing in front of my room (it's a second story bedroom and there's a living room below the railing with the ceiling two stories high), sorry if this is confusing, but basically, there's my bro, dressed in an outfit he sometimes wore, turtleneck knit sweater (he liked his clothes posh) and he's floating on the other side of the railing above the living room. I say to him, "But you're dead. What are you doing here?" He's smiling, happier than ever and says, "You've misunderstood. I'm still alive. I'm living in Europe now." He mentally showed me where he was and it looked like Frankfurt Germany on the super zoom Google Earth like trip he took my brain on. This was before Google Earth, or at least before I knew of it. Anyways, it kind of comforted me, although I don't know what to make of it.

Still here.
