i am so sorry to hear about the loss of your dear maggie....please do not feel responsible....it sounds like she got cast in her stall...many horses do this...it is not your fault...she will be at the rainbow bridge waiting for you...i also feel for your dad...having to make that decision is very difficult and a strain on your emotions...you will eventually find another horse to love...not to replace maggie,but to share new affection....don't give up!!! i know this is hard for you now...go ahead and grieve...it is healthy...when the time is right you will go forward...and have fond memories in your heart....the deli dog
