Random Abilities And Possible Prophecy?

I have always had an inkling that I have been psychic since I was about 5 years old. I have an ability to know right away whether or not a person has good or evil intentions. I have from time to time, seen demons, angelic figures, spirit guides, (shadow figures as well as something sitting on my chest) and also have heard spirits talking to me. I didn't know what this was at first, I thought it was my own thoughts until I realized that the voices I heard weren't my thoughts at all. I recently was contacted by my dead uncle. He died under mysterious circumstances and was telling me names, places and situations which I would have never have known about, including stuff that happened before I was born. I googled the places he told me and was flabbergasted when they were real locations of an auto body shop where I would find someone involved in his death!

I also told my mom what he told me about their childhood and she started crying and told me that there is no way I would have known their inside jokes or what he was telling me. Besides this, I have had precognitive abilities, I had a lucid dream before 9-11, sometimes I'll hear conversations in my head before I have the exact conversation with someone, I'll know something is going to happen before it does and I can't explain how or why.

Recently, besides all this other stuff that has happened, I was driving in my car and I was not thinking about anything at all. A meditative state. I started thinking about the devil and how I was put here along with other people to fight evil. This is something I have always known, but brushed off because I didn't know what to make of it. Out of nowhere, a calm, soothing voice said to me "It's all a lie! Everything evil is an illusion which unfortunately a lot of people fall for from time to time." I was then shown how the devil distracts people from what really matters, through anger, money, power, lust and had a vision of the grandeur of some major religions and how the golden chalices and expensive robes were related to that. I heard the voice again. "Distraction! All he does is try and distract you from your true life's mission to love! You have more power than you shall ever know and it is inside each and every one of you and that is what he is terrified to find out, that you know how to use your power for good!"

So yeah, over the past couple years these abilities have become stronger and although I have awesome experiences like that vision and trying to help my uncle, I am also having trouble managing them. I am done being afraid of what I see or know anymore. However, I need help on how to block other people's energy. I like knowing what they think about me right away because it prepares me for how to handle them... But in a way it's overwhelming. I have days when I just don't want to do anything because I am zapped of energy because I end up feeling other people's emotions. Long story, but I have a lot going on. Is there any advice on developing and managing my abilities? I would appreciate it!:)
