Linda dear, Parkinson's does not cause heart failure. Your Dad already had a heart problem as you say, he had had angioplasty. Your father was aware of your love for him, despite your occassional impatience. Believe me, he was more impatient with himself and could understand the reaction. It is hard not to be able to say goodbye, but how fortunate for your Dad that he did not have to suffer lingering long and feeling more incapitated than he already felt. He would have considered himself even more of a burden. Grief is necessary in order to let out the feelings we all store otherwise. Allow yourself time to miss him and grieve . Time will be the inevitable healer. If you can look at death as a continuation in a new dimension with perhaps a more perfect body, then you can rejoice in your father's transition.
