Stalked by Cyber Hacker

I have someone who has appeared on 2 different computers by the name of 'Sherman' that took over administrative rights both times. The 1st time was in March/April 2010 on my Dell Laptop right before my eyes... The screen went black & within 5 minutes my screen opened up with a new Profile by the name of Sherman with the Chess Player icon & Administrative Rights. Stole the 2 emails I had back then; I was unable to log into them & access them. I've been living in the 'Twilight Zone' ever since... I was in such disbelief at the time & had no idea what was yet to come. He totally controlled what I could and could not do because by that point he was literally remote accessing my computer. Before I knew it my cell phone was acting 'possessed'... & numerous ones to come. The beginning of living an unimaginable nightmare and true test of my sanity was just about to become 'My Reality'. The never ending day to day events were beginning to make me feel like I had lost any REALITY. I need to get my story out there to anyone who will listen. I can't be the only one that this has happened to. Last September (2011) shortly after buying a MacBook Air (gotta love my Apple devices!) SHERMAN appeared again. He is on a mission to try and drive me crazy but I can only say that WGACA. My Hacker is PATHETIC. He had to prove how 'Hacked Out' he is by actually following me from MD to FL. His obsession to continue to 'humor' me with what seems to be the 'unexplainable' but I keep crossing paths with very knowledgeable various people that tell me how easy it really is to do... Just most people don't waste their time trying to pursue anyone in such an evil way.
