How to escape obsession? I beg you to read to the end.?
Seems like every time I am afraid to tell someone in real life about my problems, I turn to yahoo answers. Most people would excuse themselves by saying they are in love, but I know I’m no more in love with this girl, but obsessed with her. She knows this and uses this against me… she knows I’ll jump like a horny puppy to help her whenever she requests, I’ll obey her every demand and do whatever she wants me to. So how can I escape this state? I used to think that dating other girls would help me but now I just can’t take my mind away from her. Please answer only if you’ve experienced this or if you have a bit of knowledge about how mind works, because I’m not interested in answers such as “Forget her! Focus on some one who deserves it” or “I’d be honest with her and tell her how I feel” because it is not that easy. Also if you want to recommend a good mental exercise feel free to contact me on yahoo messenger. Thanks a lot.
