Water leak gone wild!

Following a tragic loss my daughter and I inherited a 1970s house. After opening a laundry cupboard which hadn't been used in months because there were clothes in there belonging to my greatest love I just couldn't throw away when he passed, I found a spectacular variety of moulds, then that the hot water cylinder had leaked, then that I had to remove the cylinder, replace the floor and walls between the kitchen and laundry and floor coverings. Quite stunning if you like interpretive art, if not, and instead suffer a mulitude of health conditions including asthma, it has meant a tsunami 'ripple effect' and as you can see "she's a big job", the task is overwhelming and it's exacerbating my health on multiple levels. I usually have a carer come in 3 times a day to make sure I take my meds and remember to eat and drink to keep me well (I won't go into 'long version' of what my complicated health conditions are) but currently I can't even stay in the house and it has been weeks. I'm feeling frayed.
