Just needing to vent because I’m so stressed about the whole situation 😫

My morning has been pretty rough. Just needing to vent. I put in notice at the place I live now to move out August 1st but I’m also paying for the month of August because my lease isn’t up until September. Anyways though the place I’m moving to wouldn’t have been available until August 9th and which the place I live at now has agreed to let me stay until August 9th. I get a call from the place I’m moving to this morning and now the move in date has been pushed until August 16th and the place I am now won’t push the date of me staying here any farther. I am so stressed about it. I don’t know where I’m going to live for a week or where I can put my stuff for a week. I’m due August 11th, I have a two year old, and I’ve been caring for my 14 year old sister. Any advice would be great.
