Wow! That's a lot to deal with and then to have this nosy Nancy butting in is like salt in the wounds. I'm sorry for your loss and the difficulty dealing with a whole new family situation. Do you have any support system at all?
The part that irks me about this woman is that she's nosy enough to tell you what-for about your baby crying, but not interested enough to notice that you were never pregnant and then all of the sudden have this infant. Decent people would have simply asked if you need help knowing that something serious had happened for you to suddenly have an infant to look after. For someone like that, though, I doubt she'd even hear you if you tried to talk to her because she's too self-absorbed. I hope she reads this thread and feels as ashamed as she should. And I hope you stick around. Not everybody at MDC is like that.
