I have a history of depression, and was on zoloft for like two month. I have some memory problems and couldn't remember to take my meds so I stopped. Lately, I have been getting so anxious about nothing, and feel like something is sitting on my chest. Also, last night, I became so paranoid that I had to get out of my bed, turn on all of my lights, tv, everything. I have no idea what I was so afraid of but I was so scared that it carried over to today. I'm fine now, but I've never had that happen before. Does it have something to do with my depression or something else? There is a history of schizophrenia in my family. Also anxiety disorders and depression.
