Hang on, ftp, you think "it sounds like I have the problem and they are all normal" ??
Okaaay ... let's have a look ...
You send a Christmas card featuring a Christmassy picture of your baby.
Your family tells you it's wrong to do that. They say it's wrong because they don't do it 
You text pictures of your DS to your family.
They say they don't want pictures. Harsh, but fair enough.
But they say they never send pictures of their DCs, when in fact they do. 
Your sister screams at you until she's red in the face - because you refused a chocolate.

If they're normal, I'm a chocolate reindeer.
MH, I'm sorry you're off form today. Me, too. Dunno if it's the weather or the season to be jolly - probably both, tbh!
I need someone to tell me that 'normal' brothers & sisters, and good friends, would make an extra effort to stay in touch with their sister when she's isolated, broke and confused - instead of steering a wide berth.
Actually, I don't. I've just told myself!
So that makes at least two of us, ftp - we know how to show love/concern/care, and it's not what our families show us.
