<human>: Provide a brief overview of the text.

My friend [17F] threatened to kill herself after finding out I am talking to other people. She became obsessive and wouldn't listen to me or her best friend. After making me stay up till early in the morning. She wouldn't want to listen to me or her best friend and now she is wanting to have a normal conversation like nothing ever happened. She lives 4 hours away from me and we skype every day or so. We have been talking for about 3 months now.
 
She was mad that I was friends with other girls apart from her. It has scared me a lot and I don't know what to do and I am scared to do anything.
