Sir i don't know i am suffering from any psychological problem or not. But i am mentally attached with the girl very badly i want to get rid of her but i am not able to do this even every time my mind is always thinking about her. Which causes suddenly change in my behaviour from happiness to sadness. Which is directly affected my digestive system daily routine, health, etc. Even if these things getting out control in my mind then i  had to attempt suicide. But i want to control these thoughts and i don't want to suicide or any harm to my body.
