Well....Nothing wrong with going to the Doc.
Alcohol, drugs and the like are often self medication, and we do need some practical direction from a doctor if this has gotten out of hand...
On a more positive note:
I have known people with this same problem. I was married to one. For the most part the doctors seemed eager to prescribe some drugs and otherwise just did not believe she was "hearing voices from the dead".
What she told me was that while around me the voices stopped. She could sleep normally, though the problem was still there. She found me to be one of the only people who believed her, and was willing to accept what she said as truth. I think that is possibly 90% of the problem, just finding anyone who doesn't think that hearing voices is because they are crazy.
That may simply be 90% of the cure too..
However, the idea is to simply exercise the "talent" a bit. This can be simply telling others what you hear, when & why.
I sympathize, and understand because I have a different but similar problem. My mind picks up on what others are thinking. In a way it creeps people out. When I am speaking to them I feel as if the thoughts are my own, but in fact it is not often my own mind thought. I had to train myself to know the difference. Even when there is no conversation, I would speak and it would be exactly what the person with me was thinking..word-for-word. Harder yet, while sleeping my thoughts would mingle and my dreams would be that of my wife...
It was creepy to say the least, even to me.
I don't really want to have this "talent", but there it is. I trained myself to be objective and distinguish the difference from my own thoughts that that of others. Learning to meditate, simple as that is, went miles in helping me solve this problem.
Those who hear the voices of the dead, are also just as sensitive as those who can see the color of another person's Aura. The problems range from one end of the spectrum to the other in senses. And as usual all the doctors want to do is drug the person as a cure.
To exercise a talent like this one must first become grounded. The OBOD course does this very well and then offers insight to using oracles. The use of an oracle is the way to exercise the "dragon" or talent. Each of us will find an oracle or even create method that can work for this, simply.
Once brought to a positive goal and use the unwanted problems go away or become manageable. Rather than popping up in disturbing ways, one can make use of this part of the mind and using the light body and other body related methods, balance the mind. We always still have the talent to see or hear things, but rather can become healthy and positive about it.
It is important to know:
This is a proactive way and as I mentioned, 90% of the problem is just finding others who believe you and understand. The rest is personal work. There is no "magic" or "spirits" involved really in the work, from the body stand-point. From the mind standpoint one needs to get a grip on what is really happening. Most people who hear voices of the spirit realm are hearing the impression others have left in our apparent world. It is not imagination, it is simply sensitivity. There is nothing to fear from it.
Understanding the fact someone can see or hear another's feelings and thoughts isn't any kind of curse, there is no devil or other bad thing. It is all totally natural.
What plagues people is the brainwashing of Judaism telling all that anything of this sort is "evil". Nothing could be further from the truth.
Like any problem, understanding it is solving it. It however is a problem we must take to task for ourselves. Dragon-work is one of many ways, as example, to balance the mind-body, so is Druidry. It is good to start by exploring the many spiritual and mind-body methods and find one which works.
Most others will never understand, and once you have learned to manage a talent of this kind, you may find yourself being looked at as some kind of magical person. (better than being looked at as a nut ball eh?)
Most importantly, you can go on with your life, and put this "problem" in its place.
