Hello John,
I just wanted to say welcome to the NeuroTalk Support Groups.
I'm really sorry you're dealing with so much.
What is happening to you right now seems very complex and it must be very difficult while you're still recovering and learning to live with your own serious health issues. It almost reads as if you're blaming yourself in some ways for your former partner's own health issues.
Now that you're apart, and she is in the hospital, have you considered getting some professional counselling for yourself to help you deal with everything else that is going on in your life.
btw, we do have a
TBI/PCS forum here.
take care there. Please try to get some counselling because it just might help you make more sense of what has been going on in your relationship.
