I've been having a problem that I'm smiling (but not feeling happy) about absolutely everything. I would go out with a friend who I don't even like as a person, and can't stop smiling. I physically can't stop it. It happens when I'm reading bad news, good news, anything. I would put my hands on my face to somehow stop it but I can't. It's like my face has a mind of its own. It usually happens with any type of emotional stimulation. I read that innapropriate emotional responses is a disorganized symptom, but I've never had them and I don't know if I can have just the one isolated symptom. I have had an intellectual decline lately. I am no longer capable of understanding things like in books for example. I will get a brain MRI but if it's not something treatable or is a SZ symptom I'm ready to just give up.
