My son who is mentally ill, undiagnosed under CAHMS, is refusing to wash and change clothes, sleeps in them . Been like this for about 6 weeks, I find it distressing ....Can anyone explain or any experience of this? Son is lashing out tonight as his Dad is negotiating that he must shower....I fear he may be sectioned tonight ...as exH dialled 111. upsetting and frightened where he may end up....
