Very sorry - what an awful thing to happen. I couldn't bear to talk to anyone either when I lost my boy and then a few weeks later I couldn't stop talking about him. My friends were amazing - letting me have space and then letting me rabbit on - so I hope you have some good friends who will support you in the same way.
Utterly heartbreaking for you, but maybe think that if he had a choice, it might be the way he'd have chosen to go. No pain, no suffering, no protracted visits from vets. But he does leave an unfillable hole in your life.
Was he your only horse? I know a lot of people would disagree, but when I've lost my horses (admittedly not under such circumstances) I found being around the yard and helping out with the other liveries kept some level of normality about my life and did make the loss of mine slightly easier. Cutting myself off completely was just too much to cope with.
He was my only horse - my first horse. I always thought that when he was old I would get another so he could enjoy his retirement and I would have something to help me through it when he went. Just never expected to lose him so suddenly and so soon - he was only 12. I can't face seeing his empty stable yet but I will go to the yard soon to see his buddies, he was loved by everyone at the yard for being so gentle and had a lot of very close horsey friends too, he loved playing with the youngsters or just chilling with his two best buds, Fox and Jim.
I am so very sorry to read this, you have had a terrible and devastating shock, I hope you can give yourself some time to grieve properly. Gradually you will start to come to terms with it and you'll be able to enjoy the lovely memories that you have of Milieu.
I lost my horse very suddenly to colitis nearly six months ago, he was only 11 and I was heartbroken. It took me a while, and I miss him very much and still get misty eyed when I talk about him and look at photos, but the pain isn't so intense now. I no longer question everything that led up to his death and feel the same guilt that I used to, however that is part of the process towards coming to terms with it. You just have to do what feels right for you. It sounds like you have a good support network as well, that is so valuable.
Just wanted to say how much all of your messages have helped me get through last night and today, I really really appreciate them. Laura - thank you for your lovely pm, my phone is not letting me reply to it but will reply once I am home and on the laptop. Emma xx
