What am I going to do, what can be done?

I have been up all night, earlier I had bit of a meltdown. My kid was calling non stop... just to make sure I wasn't out clubbing or something.. The love I have 4 my son is so much that there are really NO adequate words to describe it. But today I just needed to concentrate on a few important things. I'm tired and have been searching online for affordable Apartments.... not having any luck. And I will tell you, that going from owning your own house to sleeping on your sister's couch.. to looking into moving into an apartment is so disheartening... it hurts like hell!
