I guess I really need help. Can someone here give me some advice please? My 3 years relationship ended 3 weeks ago. It has been hell for me all this time. I had to take sleeping pills to sleep every night. I lost weight like crazy.

I really want to move on. But I think one day we will still have a chance. I know we will have a chance. It's just that she just started working 2 months ago and I still have 8 months left in my studies. I think we are meant to be together. She has a totally different lifestyle now. She goes clubbing with I don't know every weekend. And I feel worried that there might be someone else. But I really don't know. I ask her about it and she denies having someone else. And she says things like if I ever find someone else she will kill me. All these things made me still have hope in this relationship. I still love her very much. But I am not sure about her.

Help me please. Wake this shit out of me.
