I have been in a relationship with a girl since 2017. Then for work purpose I moved to other state. She started fighting on everything. Then she stopped to talk for 3 months suddenly in year 2019. She will not pick phones neither will reply. I was dying for her meanwhile. Then again in june 2019 came back to talk and I thought everything will be normal but again she left me after fighting and didn't gave me a chance to explain. Then in september 2019 I came to know she is in different relationship with some guy. Later I came to know she was with relationship from august 2019 only. Meanwhile all this time, I lost sleep. I was unable to sleep. I will remain awake all the time. And even if I get little sleep I will get nightmares. I had an average of 30-40 min of sleep daily only. She came back in november 2019 to me and promised me that she will never leave me again. I told her everything, how I was feeling. And how low I was feeling that I would consider killing myself too. For her only left all good job offer and decided to come back to delhi, I had resigned from job and she knows that well. But she left me again in january 2019 for the same guy. And told that guy that I emotionally blackmailed him. For some reason I had to take train instead of aeroplane and for those 3 days I kept on crying on train. When I landed back in delhi I was hospitalized as I was getting unconscious. Doctors told me he to relax. Then she came back again in april and again the same promises and she left me in june. For all these times she projected me wrong. I knew that she will leave me but I have become too dependant on her. I can not even think of living without her. I keep on constantly crying. I have lost confidence. I can't talk anyone properly. If someone says me anything I breakdown. I am unable to focus on anything. I know she doesn't love me. But still I am unable to unlove her. I am seeking help. Please help me. Please help me to get out of this cycle. I am on verge of destroying everything my personal relation my career.
