For the past two weeks, I've had intense mood swings, including euphoria, depression, anxiety, irritability, and rage. I've been suicidal on and off since then. It was most intense on Saturday, but today hasn't been easy. And then the "hallucinations"...in recent times, I've been having strange perceptions multiple times a day, many of which logic tells me are hallucinations. I've seen a rather steep increase. Over the past week, I began having cognitive issues. It started out innocently enough, I couldn't find the word I was thinking of. This happened multiple times a day. I complained about it to my pdoc when I saw him on Saturday, and he told me that it was probably mood related. Tuesday, I went back to class. I couldn't understand what people were saying when more than one person was talking. It sounded jumbled, or if I could make it out, it made no sense. I gave up on trying to figure it out pretty quickly. I lost my ability to focus on lecture material, and I've pretty much sat in my chair like a vegetable the entire week, pretending to listen to the lecture but not comprehending any of it. I have an exam in a little over a week, and I'm scared. Also, people look at me strange. Like they think I'm crazy. I add to a conversation I overheard, and it abruptly stops, and I think that maybe they were talking about something else...

Does anyone know what this might be? Especially the cognitive issues? It is really distressing me. I can't complete my program if I can't think. I think the issue is mostly due to poor attention. I understand my own thoughts perfectly, it is just other people that confuse me.

Is this related to psychosis? Last time I really lost touch with reality, I had some issues with confusion and not knowing what building I was in and stuff, in the beginning, but it wasn't nearly as bad as this.

Does this sound like something physical? Could I have a mineral deficiency, or a brain tumor?

I'm really freaking out. Thanks.
