Your dad and you have been let down by the hospital...he should not have discharged back to home with visiting carers with his lack of ability to do anything on his own fraility and vulnerability and someone at the hospital has not done their job either in referring him to be assessed properly or at all. All of us who have had to take the care home decision know how hard it is but it is taken with kindness in recognising it it is the pwd best interests and it is the same for you. You have done a wonderful job keeping your dad safe now is the time to have a team and support around your dad and you. We have all had those tears...the frustration...the sadness at the realisation a home is needed now..the anger at the dementia..trying to keep all the balls in the air...mental and physical exhaustion...the list goes on...so many reasons for the tears to eventually come and I send you a virtual box of tissues and hug.Thank goodness your GP was so concerned.
