She may just have some king of mental illness. That is a very real possibility. (My husbands family - including my husband and one of my 4 daughters is mentally ill - so I know how hard that is on a person) As hard as it is - try to treat someone like this with kindness (and pray for them) - who knows what problems she has that are causing her to be so hateful. But what ever they are you know she has to be miserable to act like that. Try to shake it off, and know that you have a lot to be thankful for and maybe she doesn't - or at least isn't able to see the things she should be thankful for - like precious little dogs
