Gerhard my deepest condolences to you and your son and family. .this pain is unbelievable. . I m going through it right now first hand.. ppl say it get better everyday. Well three months ago I hit rock bottom and still trying to get up and face life.. the fact of the matter grief and at your pace.. the acceptance and peace will come.. it will then it goes and come again and again. But i m sure you do not want to see her suffer anymore.. as some one said to me why do you want your mom to stay alive for you to see her suffer? They are right ..life is like four seasons..i pray you find comfort .. my found mine with taking time off and reflecting on the good times..but must say it is very difficult. Take care and bless
