Lets just say I had fallen in love with someone way out of my league. It all started with foolishly asking her out for a date to forget someone else and then not having guts enough to cancel. Anyway, my feelings got too strong at the end when she was about to leave my country forever. I never confessed to someone before, so I decided to experiment a little, thinking it would be easy to forget if things go wrong. I asked her out for a second date before she leaves. Turned out she never liked me, we had a little argument, I was forced to confess and after that we stopped talking with each other. Unfortunately, no matter what I do, I can't completely get the whole situation out of my head. She was my co-worker, and her memories are everywhere. I have recently overheard other co-workers making fun of me. More I remember what happened more I feel worthless and suicidal. What should I do to deal with the situation before I eventually change my job?
