I am so sorry to read this. She was a beautiful mare and this is a very difficult time for you right now. Her last few weeks of happiness and all the happy memories you have will stay with you. Big big hugs to you. xxx
She was a beautiful girl, and you were lucky to own her, but likewise, she was lucky to have a wonderful owner who put her needs before her own heartbreak.
Very sorry to read this. You were so very brave to make that sort of decision.
Im sure AmyMay will be thanking you from where ever she is now. Just remember to cry when you need to and let yourself heal at your own pace. The first few days are the worst but its nice once thats over to think about all those funny moments and glorious times you had together with a smile!
Take care.
