Re: HELP! How can I help my mare to cope with a night alone tonight?
What's her usual routine? If she normally stays out, then I'd leave her out, if she's stabled at night, then stable her, so that at least she knows that some things do stay the same.
Would you be able to get out shopping today and buy a calmer? If so then that will probably help, or try to contact your vet if you think she'll be really freaked out.
The other thing would be to ask someone with a horse she knows if you could maybe 'borrow' them for a day as a companion.
It may be a lovely night for camping out but you'd get very little sleep, lol !! Also if you're a bit nervous of her reactions, she may well sense what you're feeling and therefore be even more stressed about about being left on her own.
Can't think of anything else, but I hope she'll be ok - she may surprise you and be not bothered at all.
