Mildred's Maid
I maybe completely wrong but the undertones from you are very negative, even when others have tried to reassure that this poor mare has only been with you a week. Disappointment is understandable but, If you are honest with yourself, are you experienced enough to try and support this mare or send back before you get too attached and possibly cause more issues. No judgement from me whichever way you go.
