Only friend stole from me 😩

I’m so hurt and idk what to even do! I’ve known her for 3 years. It was the first time she stayed overnight and I had rent money in my car to try and track down my landlords. I have tried to think of how else only 100$ of the 800$ would go missing and it doesn’t add up. I don’t even want to hear her lie to me so I blocked her number and social media. If a random person was going to open my wallet and steal money they would have just took it all. I’m so flipping upset about this. She’s a grown ass woman and says I’m her only good friend. I guess she has none now...
