I used to have this problem to the extreme! I was so completely obsessed with it and I got so into it that I started imagining and wishing that it was real and it basically took over my life for about 3 years! I even cos played at school on a regular basis. I got into it because I had moved to a new place and was really shy and had a hard time making new friends. I have absolutely no idea why or how I stopped all of a sudden but I did. One day I just decided to do something else and that was that I quit cold turkey
. Maybe I grew out of it and maybe you will too but then some people are 30 or 40 and still like it that much. Just make yourself do other things like reading a normal book or going for a walk or hanging out with friends. It's okay to like it still just don't let it consume your life
