I lost someone important and this is my story of grief

I lost my dog and to those it may not seem like a big deal. To me its life shattering because everything has changed. Her name was Autumn Marie she was my world, my daughter, and my reason for living. We were blessed with having in our lives and by we i mean my family. But my whole family knows that she was really my dog and she and i were best friends. I am sad to say she died in my arms on September 12 around 18:00. I cant believe it happen because it hasn't hit me that my world has ended my best friend my daughter the reason my heart kept pumping blood for the past 8 years is gone. I cried all night because why, why must she leave me. She came into my life right after I lost my grandfather, he was my other best friend in life. She helped me through that and so much more. I surfer from major depression, anxiety, and PTSD.  This was all clinically diagnosed by my therapist and psychiatrist. She helped me through that all the medications, the substance abuse, the suicide attempts, and hospitalizations. She was my reason for continuing and never giving up. But what now ? What do i stand for what do it fall for? I'm feeling so empty but today is only day 1 and i will keep fighting for her and to show her what she has taught me. She taught me how to truly love something and myself. To never give and make her proud no matter what. These 8 years with her will never be forgot but remember everyday and i will continue to push on with my drive in life. The only thing that keeping my alive inside right now is writing and photography because she was right next to me when i would stay up writing or editing pictures. So they remind me of her and her being by my side. I will never forget you Autumn. My favorite quote is "Ever thine, Ever mine, Ever ours" its from a love letter from the 16th century to wife separated from her husband by war and devastation. To me that's how i feel like with Autumn we are separated but our love will never leave. Its not goodbye its ill see you later. Rest in peace my angel I'll be with you in time. -To Autumn from Olivia
