My Third Eye Have Been Blocked For 10 Months

Since August of 2012 I lost my imagination and had trouble visualizing things. Couple days ago I hooked up on the internet and it said my third eye is blocked. This never happened to me before, I wonder if someone drain my energy that I am unaware of. Before I lost my imagination in May of 2012 I used witchcraft without knowing that it was a sin that night later I heard a voice that said it was going to haunt me since then I have a feeling that I am being watched and I get a drain of energy and feel extremely tired and I'm also having trouble letting go of a karmic relationship that I think is also is draining the energy. Later in May 2012 I began hallucinating I can see my fictional characters talking to me while I was playing with my videogames talking to friends etc and I had a vivid imagination until August 14 2012 that's when I lost my imagination since then I haven't been able to write a book which is keeping me from my calling, I prayed that God will give me my imagination back before the summer starts. But I heard that you cannot clear your third eye if you haven't cleared your lower chakras such as the root. I want to break cords from all my chakras so I can feel free again and get my imagination back but too bad I can't visualize. I can barely visualize at night, when I am very sleepy I go to to sleep and I see chakras in my third eye but it only last for a couple of minutes and I'm not even thinking about the chakras when they pop up in my minds eye like that so I am wondering can I clear and balance my chakras when the images pop up in my minds eye. I try listening to the om sound but I don't know how to breath deeply without me gasping for air
