Both Parents are Flakes!!!!!!!!!!!

My mother lives out of state & shouted excitedly "I'm moving closer to u for baby!" when I told her I'm pregnant.
My dad lives half the country away, and every time I've talked to him over the past several years, he says he's moving here if I ever have a baby. 
Now neither are moving closer.  They LIED.  I didn't really expect them to move here, but I feel extremely lied to!!!  like, bait & switch!  LIARS!
Now, come to find out, my mother is about two months away from living in a homeless shelter.  And doesn't want to move here because "it's too big a city."
And I have this enormous amount of guilt because I can't help her financially.  But she's a LIAR anyway.  ??
