Stress

We finally got the spare bedroom cleaned up. It was a nightmare how BIL left it. All his stuff is now packed in boxes and moved out of the way. I went through 4 of the 5 boxes of stuff I had in there and got it all into one clear tub. The other box was put out of the way as it has all my old Barbies and accesories. The floor is swept and no cig butts left to be seen. I didn't clean under the bunk bed though, but it is staying, so not too worried. Now a couple friends of ours (and their baby) have had their electricity cut off until they can pay the full amount they owe. They are asking if they can come stay with us. We are trying to get this house and the bedroom ready for Annastasia's arrival and money is extremely tight. We just can't have 3 more people living here right now. I feel really bad to the point I am crying, that we can't help them out. It has been such a hot summer and they have no AC now. I wish we could have them stay, but if they can't pay their bills, how could they help us if they stayed here? We would be having to provide food for double the amount of people, when right now we can't even afford to buy a loaf of bread. The do have food stamps and wic, but even if they did get their own food, there is no room to keep enough foood for 5 adults and a baby in the fridge or the pantry. We barely can make our food fit sometimes. And the increase in electricity and water would go over our budget. Plus not knowing how long it would be for. We have to finish cleaning and rearranging two rooms, plus get my aunt and uncle to bring the crib and we have to move a dresser from our room to Anyas. Once the crib and dresser are in there, it won't be much room for anything else and we will need to get everything set up for when she is born, so they won't be able to stay in that room then. I just feel so bad having to say no, but what are we to do?
