I've a family member (lets call them A) who suffers from severe Mysophobia since the start of the COVID outbreak in March. A is convinced that the home is full of germs causing them to avoid touching all surfaces in the house, walk (sidle around the house) in a set route, take 30 mins to wash their hands, take 2-hr long baths, avoid doing any house chores and the list still goes on. It has been 9 months and A's condition continues to worsen. It has gotten to a point long ago that it has disrupted A's daily life and also the lives of the family members. The family members, especially the parents, are distraught by A's condition. A's parents have tried talking to them about their condition, but any reassurance and advice they give always goes over A's head. A is well aware of their condition and seems to be "content" with their current situation and shows no signs of wanting to get better. When their condition is brought up (always gently at first) they become extremely defensive and hostile. When questions about A's condition are asked (to understand their situation better), they give nonchalant answers and excuses which are very infuriating for the family. After that, the situation always escalates to shouting fights that doesn't make any positive progress. Another thing I should mention, it also seems A is selectively(?) Mysophobia, where they are ok with certain things being dirty, such as their laptop and their phone while everything else is dirty to them.
We are at loss at how to handle this and our lives for the past 9 months have been highly stressful. Since talking doesn't seem to be working, we have resorted to pretending A's condition doesn't exist to live a "semi-happy" life. However, we know this will not work for the long term, as rows happen usually twice a month.
For those who have family members with Mysophobia, what are your methods of reassuring and helping them? And is being "content" with Mysophobia a normal thing? We'll appreciate any advice or sharing of experiences. A's condition is starting to tear the family apart and personally, seeing the parents suffer is heartbreaking.
