Sheba, I hope all is well and he went to the clinic! As you know I recently experience my dad denying his illness and making him go the doctor. I hope that your dad will go.
Thoughts and prayers with you and as someone posted in "my string". The Serenity Prayer - We have to accept the things we cannot change, have courage to change the things we can and the wisdom to know the difference. We cannot control another persons behavior.
Gosh, I know how hard that is with these circumstances! I hope he decides to go and yes, as wildcat suggested, don't forget to tell him you love him!
