Well, I can say with certainty that it wasn't the lexapro or the singulair that caused a visual disturbance that caused difficult child to think she was seeing bugs on two occasions. How do I know this? Because difficult child informed me tonight that she hasn't taken her medications for 2 months. When I've given her the medications to take, she's acted like she was taking them, but threw them away. Besides the obvious, those are drugs with high co-pays and I literally just threw that money away. She claims that they made her worse because she was being forced to take them against her will. She is refusing to participate in therapy. None of the things that work for other people work for her because she's not normal. Her words. It's also not her fault she's depressed. It's because of the way everyone in the world treats her. I swear I don't know what I'm going to do with this kid.
