I have lost my best friend!

The other day I took my fine four legged pal for a ride, and I must say she was probably thinking I was more of an enemy then a pal by the end of the ride. You see, I did not like the farriers job on my horses shoes, so I had them pull them. She was a bit tender after this experience, but I figured that was rather normal, but still something was not sitting right with me as I looked at her hooves. Well, regardless, I tacked her up and rode her, scolding her for her laziness, although she was trying hard to listen to my commands. Pretty soon she was sweaty and coughing so I stopped her a got off. Then my trusty steed started to wheeze and heave, and make all sorts of sounds. I then walked her towards the barn, only to notice a bloody spot on her foot and her limping. Yikes, I felt so bad I was ready to hurt myself, what had I done! I should have checked her over better. Upon further inspection, the lady I board from had feed her alfalfa which she is allergic to and she couldn't breath, she had tangled her foot in the fence and had a cut, and the farrier completely messed up her feet, causing her to be tender on all of her feet and unable to be ridden for two months!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So I paid for a vet bill, some expensive medicine, my Mom to come pick her up and bring her home (to where she has no allergies), and I paid for my farrier back home to fix her feet (which will take quite some time). Now my best friend has cost me lots of money and moved back far far away!!!!!
