I suffer from depression and anxiety. I've had intense therapy, ECT, and am on medication. It's been just over a year since I had the breakdown. Recently I've started to feel better only to relapse a few days later. The change over takes about two or three days and the depressed or improved mood lasts a day or two longer. The highs are getting higher and the lows are getting lower. I don't meet the criteria for bipolar. My highs never get manic. At first I would get very depressed and cry for hours when I realized the improvement was temporary and I was cycling down. Now I am more resigned to it. I can't plan anything. I make doctor appointments and can only hope it will be a day I can get out of bed. Is this a sign of improvement? Am I becoming bipolar? Is this common occurrence in depression? Any insight you could share would be much appreciated.
