Welcome to PsychCentral, iCrazyLisa. It sounds as if your lost of life's joy and motivation are a result of the heart attack--that it caused you to lose confident and diminished risk-taking. Or have you been diagnosed with a mental health condition, even one pre-existing your heart disease? I'm wondering which contributed to which ... Physical illness leading perhaps to depression of a mental illness causing physical stress, culminating in the heart attack.
Why does you doctor contribute to your getting better?
