My friend always gets mad at me for little things that none of my other friends do? It makes me sad when she is always upset?

Like when I sleepover at my most of my friends houses they let me use there toothpaste and I forgot toothpaste and used my friends without asking and she got really upset with me. Or before it was using shampoo and conditioner so I started bringing my own. I just feel like it’s always something while any of my other friends I can use there stuff if I sleepover and they can use mine if they sleepover at my house. I do know that she thinks that she has OCD. But I just feel like I can never do anything right with her sometimes.
