I was just wondering if you are in to any drugs. I know DMT can give me effects way after I've done it. I've gotten the mosquito buzz before.

If you haven't been on anything, I suggest you see a psychiatrist. I don't know anything about shamans but talking through these things helps. The first thing you did right is seek help. Now, you need to go see professional help. I wish I could convey a caring tone in text, but if you are of clear mind and you're hearing voices, you need to talk to a doctor.

Have you considered that it may be a spirit living in the house?

I hope you are able to overcome this obstacle, I would love to read how you were healed in this forum.
