I am so glad that your father is doing so well! It's amazing how much they have advanced in cardiac care and THAT is a wonderful thing!
IMO,... it sounds like you're starting to fall back into your old pattern of getting too involved again.
Your father is going to be fine now and the cardiac unit will be making sure he is taking care of his health by have him attend his cardiac rehab program, which is wonderful for him and hopefully change his life.
You and your father have had wonderful, positive conversations BEFORE about your mom's bipolar illness that turned around and turned ugly in the end...remember?
You're mom has been handling all of stuff with your father very well to your surprise and going to all of her appointments and again you remain hopeful. She is learning about the outpatient program and is showing some type of interest in it.
I would encourage you to stay on your coarse of keeping your distance and letting mom & dad handle their own issues so you don't end up on the vicious circle that always has happened in the past. You're trying to handle this in a new, healthier approach for everyone remember?
So I would encourage mom to attend the outpatient program by telling her that it is Perfect Timing! ...Dad is on his own program that will take him away from home for a certain amount of time each week with his rehab and that she should also go to her outpatient program and concentrate on getting her support and education for a healthier lifestyle as well.
AFS, I think this is your answer and perfect timing to get your point across that we talked about in a previous post.
Hope everything goes well!
Keep us posted.
I'm glad that thing are looking up for you and that your parents are taking more control of things.
Best wishes. Continue to keep us posted.
