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

Sorry this will be long, but thanks for reading if you go through.
Last year in November I met a girl through another friend. She was one of the coolest girls I have met and we became close friends very quickly. I can basically say I fell for her but I didn't tell her in fear of our friendship. Then, my best friend met her three months later and he basically scooped her up and they have been going out for almost a year now. Since they are both very close friends to me, it's common that we all hang out and I can't see them together without it hurting me. Here's where it gets weird.

My best friend (the male) has never had a relationship without fights. They fight a lot it's clear that he is usually at fault. After hearing her cry multiple times I eventually told her I loved her and she wasn't surprised at all, she said she expected it. Fast forward another few months of just talking to each other and enjoying each others company. 

Now and she is having anxiety attacks and we're both basically going crazy. The reasons are way different but her relationship is eating at her and I'm in between two close friends and I'm in love with one of them. We hang out and talk everyday and she means the world to me. I don't know if I explained the situation exactly how it is but I'm looking for input. How can I help her, how can I help myself? I'll add edits if needed.
<bot>: I'm in love with my best friend who is unhappy with her relationship with my other close friends because he is an ass with girls. We're both losing it for different reasons.
