Leaving me Alone

So, yesterday night my mom had to go out to a class, and my dad had to go out to take my brother to his basketball. My dad told my mom that I could stay home alone so I could do my homework. Right after he said that she went pale and her eyes almost popped out of her head, almost having a panic attack about him wanting him to leave me alone. If she doesn’t leave me alone, the how am I going to show that I can be trusted to be alone at least for an hour? I couldn’t stay alone, I had to go to my brother’s game, so I couldn’t really do any homework. I went to sleep later than I have been going to sleep lately. So today I really feel like cutting, and not eating anything at all.
