I lost the girl who meant the world to me now im lost

On Dec 12th 20018 I lost the one person with whom I had pinned all my hopes and dreams on, the one person I had been totally honest with since the beginning of our relationship, she made me become a better person to want to become better for her and to show her it's possible to do.
Sophia and I had a relationship some would say wouldn't work or wasn't right. She was 24 and I am 58 she was addicted to heroin when we met and I use meth. The first night we met we talked for hours about everything I thought it was unreal how this girl could seem so worldly at such a young age.
He was sentenced a week ago to 31 years in prison. But that doesnt bring her back . I miss her tremendously . I feel like I did before her and I met directionless no purpose no joy or laughter just an existence that seems to have a future of loneliness and sadness ahead . Meeting other women holds no interest to me just makes me think of her more. The places I see remind me of her and the times her and I spent there, be they good, bad, or uneventful. It's been almost six months since she died and I still wake up crying, can't look at a picture of her without crying nor talk about her without crying, just writing this is extremely hard. I feel lost in this world without her
