Mom's flooding damage

Hi guys.  My Mom's bathroom recently took some water damage due to a leak between the tiles and the shower tray. It affected the joints and beam and the stability of the entire room and possibly the entire house as the plumbers think this is the beam that runs through the house.

They are doing there best to try and fix this beam, put in support joint and rebuild up the wall.

My Mom is in her late 70's and can't afford to pay it. I am out of work due to surgery and may not be able to return and am waiting to see if I even qualify for sick benefit which they don't think will happen.

I am using my savings of 1000 towards this but this still leaves the rough estimate at 3500 and we have no way of paying it as the bank refused both my mother and I due to neither of us working.

We are getting along by washing ourselves in wet wipes. My Mother desperately needs a working bathroom and water due to medical issues. We don't even have a working toilet at the moment leading to kidney issues for my Mother and I.

I don't want my Mom to get a worse illness from this and lose her.

I am begging you. Whatever you could afford to give or even just share the story. Please help.
