Memories

I wish I could say that I was completely over this but I'm not. There are times at night when I'm just laying down and all the memories of the guys who have stalked me by harrassing me and by that they called me, texted me, called me names, manipulated me. There was this one that harrassed me for 2 years I was lucky I had 2 best friends that stood by me through all of that and helped me get him to stop however they only thought it went on for a year they didn't know it went on for 2 years this guy was just obsessed with me and had a huge crush on me it got worse after he didn't go to the same school anymore we had been friends for 2 years just last year march of 2015 after he made a fake skype account to try and get to me I finally called hiim and said that if he didn't leave me alone i would call the cops I haven't heard from him since. Then this one other guy that I haven't talked to at all he was the same way called, text, skyped, called names and since I recognized the signs I blocked him on everything quickly but I don't know why these memories won't go away it just sticks no matter how much I try to get htem to go away.
