For the past 6 months I have been having daily problems with memory problems which have been escalating of late to include issues with my judgement. Its gotten to a point where I no longer can read a book as I forget what I have read the previous day. I am finding I am fixated on worrying and my mind is buzzing, sometimes an actual electrical buzzing. There is no silence other than when asleep. I wouldn't say I was depressed before but I am now as the memory has affected my ability to work or social activities. There are times I do have suicidal thoughts of late as my life is literally vanishing in front of me. I lost the house keys the other day and found them in the ice box and I have no recollection putting them there. I used to be always in control of my environment and now I don't remember anything from yesterday unless it's written down. Is this depression or something more serious?
