how do you go on without your ride or die

I just lost my girl that I’ve spent the last 5 years of my life with. We were inseparable. She was my world. My ride or die. She went into the hospital with neck pain and died less then a week later. She was 31 years old. People say time heals all. They are liars. Eveday that goes on gets harder and harder. I don’t want to put my parents through the same pain but I’m to the point that they shouldn’t want to see me in pain anymore. I’m 32 years old and I’ve attempted suicide once and it didn’t work. I’m to fucking healthy. How can I do this fast?
