Hi and welcome to the forums @Notcara 👋
Its a tough situation, to be sure.
My hubby became ill when he started a weight loss effort some years ago. It has veered off into seriously eating disordered behaviours, which he believes are a healthy lifestyle change, and we can’t do anything about it without bringing the roof down on everything we hold dear ..... I suspect there is anxiety and depression fuelling this, but without a diagnosis we (kids and I) are trying to hold everything together well enough to keep walking along with him. There are definitely recognised OCD behaviours mixed into it all, and perhaps one or two other things.
Coming to terms with a changed life, particularly if you didn’t see it coming is really hard. There are others here who have experienced something similar. You are not alone. Being here amongst s community who share the issues and understand the pain and complexity of it all makes a very big difference.
We have a thread here with caters hints and tips to help avoid burnout, and social threads to chat with others when you need a listening ear of a shoulder to cry on for a while. Hearing about how others manage the difficulties of their own situation can provide advice, encouragement, empathy and companionship on the road.
Keep taking care of you. You matter too ❣️
