Just take a deep breath and walk away for a little bit.
I have had similar but different experiences. I lost an Anaconda to a stupid mistake, lost a lot of money. But I just took a break for a day or two and my obsession with trying to get my money back took over.
Rest assured, if it was a player in this group who killed you, he will not be here long. You have to understand that there are assholes in the world that want nothing more than to spread around suffering. Doesn't matter where you go or what you do or say. They will find you and they will try to hurt you in some way.
That is just the state of the world today. Once you accept that fact you can mitigate your losses by being prepared for it. You can call it paranoid if you want, but it's just a fact. I don't live my life afraid of people trying to hurt me, I'm beyond that. I can't be hurt, it doesn't matter what they do. I pity them that their lives are so horrible that they feel the need to attack others.
This applies to game and IRL.
Forgive my personal philosophies on the board.
