I feel broken...

My classmate accidentally gave an ip address to my minecraft server to someone else and asked them to destroy the world of the juniors. But it was mine and he destroyed my builds and all my stuff is gone. My villager and pets, i treated it like it was my home. I felt so peaceful until today. I want to have revenge but i dont know how. I also cut myself as I think its a bit of my fault too as I was afk at the moment. I cut myself based on how many was killed and how many buildings were destroyed. In total, i cut myself 21 times. I just need emotional support here. 😢 I know it is just a game but I just feel really connected to the world I made ;--;
