Codependency Support Group
Codependency is defined as someone who exhibits too much, and often inappropriate, caring for another person's struggles. A codependent person may try to change, or feel shame about their most private thoughts and feelings if they conflict with the other person's struggles. If you are on a journey towards self-love, this support group is for you. Join us and find others...
Having 3 open heart surgeries is brutal to a body, and I would worry more about having any more such surgeries instead of worrying about death.
I say the prayer for you and for him is to have patience, and let God do all the worrying about the future.
