Re: My Dad
Perhaps it is more related to unresolved issues with your father prior to his death? The subconscious mind is a powerful thing, and since you were estranged before his death I imagine there was guilt involved after his passing that easily can be affecting your health and the slew of 'bad luck' since. People are fairly oblivious to how powerful the mind actually is when it relates to their own reality -- maybe an honest conversation with yourself to your father, your regrets, hurts, etc would go farther towards helping you resolve what is obviously still weighing heavily on your mind.
I suppose the lure of psychics and mediums is that a weaker mind would rather have someone tell them a 'truth' they can hang onto and believe instead of frankly dealing with self on an honest, practical level. Why pay someone for an answer you already possess?
Your father is not hanging around, poking at ya. Your unresolved feelings, are. Deal with them, confess, shout out your anger/hurt/whatever but just get RID of it. Forgive yourself, forgive him, and move on.
So much of health is related to the mind. So is 'luck'. Circumstance always plays into life, but how you look at it details whether or not it controls your life, or if you are doomed to replay it in an endless cycle of trying to get things right.
It is only impeding YOU now, and your father I guarantee you is not causing your health problems or waiting for you to pay some psychic to wave some incense and release him to the ever after. Light some candles if you want, talk to him, bid him adieu, cleanse yourself, weep, gnash your teeth, renounce, accept that the relationship was not as you would have liked and be at peace with it. You can only move forward, the past is done and buried.
Good luck to you.
