During this date 25/07/2014 at first i used to have my imaginary friend whom i used like that person a lot. So first on that day I was in India spending my vacation while enjoying with the imaginary person so that we both should be friends forever.I was friends with that imaginary person for 3.5 years at that time during july 2014. Whenever I am trying to make myself better for the whole month of this year s august to early september. But still it cannot work. Now I am feeling hopeless and useless because of my severe problems of that date only. Before that date i used to be fine and feel better. Now it has become so difficult for me to think of that person . So I decided to be friends with that person forever in life and stay with that person forever in life. Then,slowly,steadily and suddenly a disorder on that based upon that person came to me. It is happening to me nowadays. Because of my and that person s difference in religion. So I got a thinking and that person s disorder since that date itself. Too many times during august to early september i was trying to make myself fine from that date then it did not still work. So on that day it was a big,bad and very abnormal severe problem for me to get that person back What can I do please i need help ?
