DSD1(20) has been recently diagnosed with Fowler's syndrome. She was only diagnosed after DH insisted that she went to the doctors as she hadn't pee'd for 2 days and was in absolute agony. She was referred to urology who said that she needed surgery to widen the urethra at the bladder as well as some of the muscle surrounding the bladder loosened as they were too tight. They also found kidney damage, with one more damaged then the other.
DH and DSD1 have just had a flaming row words as the consultant had told her that she has to stop drinking and try to give the less damaged kidney a chance to regain function. She has been on the rip every Friday night since when her DS is at his dad's 
(3wks) as well as having a drink in her house. We only found out what the consultant said because MIL mentioned her worries to DH ( she thought DH knew). She's already facing losing the damaged kidney, as well as facing possible dialysis and transplant.
I get that it was a shock, but both DH and I are both 
and that she's being so cavalier with her health as well as the fact that she expects DH, MIL and basically anyone stupid enough she can think of to take care of her DS while she parties. We don't babysit except if she's stuck when she's working, so she relies on MIL a lot. If MIL says no she gets XW to do it, which wouldn't be an issue if she was reliable and stayed sober (we are the one's who have to deal with XW suddenly leaving him over cos she's had enough and DSD1 isn't answering her phone).
DH is devastated and worried about her health, but she's determined that she wants to have a young person's life with no thought for the consequences. So, despite being the person that she turns to when she's stuck, DH has been told to ef off by DSD1 and XW. We'll see how long that will last 
. I just want to shake her
