Five months ago me and a friend went to a store far away from the place we live and i bought a medallion (it looks like a Japanese demon mask or sth). I kept it in my pocket for a while. When i wore it we lost our way home and three men attacked us and stole all our money. Three days later i wore it again and i broke my right leg during training. I didnt wear it for about a month and nothing bad happened. I got excellent grades at finals except the last subject. The day of the test i wore the medallion and i didn't do well at all. Two months later i wore it again and broke my left leg. After a few days i wore it again and my girlfriend told me she wanted to break up with me. I haven't wore it since then. Do you think it can be "cursed"? Do you beleive that an item can give someone bad luck or all these were just coincidences? If so, is there something i can do to make it normal? Note that except these incidents nothing bad happened to me. Please tell me your opinion about this. Thank you in advance for your help. :)
Sorry for the bad spelling.
