Does suffering make you obsessed?

Hun, you need serious mental help. If you keep thinking and acting on impulse the way it seems you have been, you're going to really hurt someone or yourself. This girl probably doesn't like you because you scare her. Can you blame her? If she doesn't want anything to do with you, leave her alone. There are so many people in this world, too many to be focused on just one person. Please talk to a therapist about all of this. No one on here can help this serious of a situation. Take my advice and take care.
