Unsupportive Sibling?

Ali

Today my sister, who is 6 years older than me and has no children, told me that she "can't wait until they take my baby away from me".

This is my first child and I feel as though I've done everything I can to ensure that he's healthy in the womb and that he'll be healthy and safe once he arrives into the world. I'd never do anything to hurt him and therefore this was never a worry of mine, but she seems to think that because my income at the moment is low- I had to quit my job of 3 years due to health complications involving the pregnancy- that I'm unfit to be a parent and that cps will take my son away once he's born. His father still works, we have our own place and don't rely on anyone else for money or help, we've just hit a recent rough patch in money.

I just don't understand why she would say such a hateful, nasty thing like that. Has anyone else experienced hateful behavior or jealousy from family and friends? I'm not sure where to go from here with her.
