My favourite horse, Caesar, a flea-bitten grey gelding, he was my first horse and I loved him so much! The next morning I came to groom him and found him dead, the vet said that he had died from something bad he had ate. I kept on crying and crying, I'll never forget him, at least we went out for a bareback hack the day before!
I truly feel your loss and I know you won't get over it easily. But don't let that stop you from getting a new loved one, but at the same time you'll always love Buzz and he'll always have a place in your heart.
