If you were reading this post (say) that someone else posted, what advice would you give them?
I bet you'd say go for it!
Some times we are not good at taking our own advice!!
This was what I was told when a very similar thing happened to me last year when I lost my beloved first horse very suddenly and I was offered another within a week of losing him. I felt sooo guilty that I would even consider it but at the same time was quite excited about it. I did go and see the mare but she wasn't for me. I was so glad I went - it helped me get over my sudden loss.
Go for it and good luck!
