<human>: Can you condense the text into a few key points?

I don't want to go into much detail about this so I will try to make this as short as possible. Also, this was my first ever relationship I have had with someone.

When we first went met, she was amazing. Everything was going great and our relationship was just awesome. We had so many things in common; we were like perfect for each other. However, the last month of our relationship just turned sour. We were always arguing and fighting. It wasn't big arguments and fights, they were just small ones about stupid things. It wasn't affecting me though. Even though we kept arguing, I still loved her so much and I never stayed mad at her. All of a sudden, she broke up with. She said she was unhappy and nothing felt the same anymore.

I was devastated. I pleaded to her that we can work on our relationship. I told her we can make things better and I told her that I could make her happy again. However, she was just so intent on breaking things off. Knowing I couldn't do anything to change her mind. We officially ended things. The first couple of days were the worst. I had nobody to talk to at night and text all day. I absolutely missed her. My friends had no idea what to say and I was at the brink of depression. I couldn't sleep, I wouldn't eat, I was a complete wreck. 

Just recently, I found out that she started seeing another guy. I think that is what hurts the most. I just feel so alone and afraid. I don't know what to do and I tried everything to get my mind off of her, but I can't.
<bot>: GF of two years breaks up with me. Tried getting her back but she wouldn't listen. She now is seeing another guy and i don't know how to handle it.
